another one of these questions 
you cant just swap in the auto CC headunit and expect it to work. the standard (what you have) is controlled by long cables when you slide the bar accross. the auto is controlled by servos and lots of wireing.

yup, lots of little things, like how it hooks into the ecu for the readout of the intake air temp. and the sensor on the dash that detects amount of sunlight and adjusts the acc accordingly, and lots more i cant think of right now.

Killer95max .. you put an auto climate in place of your manual climate???? ... if you did I think you are maybe the 1st person to ever do this or one of them .... everything ive ever read through said that it was too complicated ..... pics, write up, time involved ????????

8-10 hours, I didnt get pics during the install but I can reopen up and show pics, anyway 2 trips to certain junkyards and alot of frustration, I can get parts from the junkyards if your interested, I could do a writeup but would be way to hard, I used the fsm's and haynes manuals too, so if you can read those you will know how to do it.

I just completed a manual to automatic climate control change over for my 98 SE. There are 3 sensors to add (in car sensor is 'built in' to unit), 2 acutators to change and wiring. It took about 6 hours to complete.
The FSM manual section HA is a necessity to do the changeover.

No need to call bs. I don't mind the questions.
The 4th sensor is the in car sensor that is built into the unit - so I did not count that.
I did forget the fan control amp. component.
The change was completed with a 98-99 auto climate control unit.
As far as the 3rd actuator - there was no need to change the intake door motor acutator.

I dont care if you call it bs or not, I did the conversion, it sounds like cumbaj did it also by the way he is discribing things, I do alot of conversions, Ive converted more then any one person has bothered to even convert on their car, basically I would agree with a prior post why would we lie about somthing so stupid?
04-24-2005, 08:44 PM

im guessing ur doing the conversion because its easier or watnot...or maybe the one u have is ugly...to be honest i got no clue wat it looks like...
but have u seen wat the manual climate thing in a 1994 bmw 318is looks like? if u can somehow customize theone u have right now to that...id proly have to kill u of jealousy...i dont have a pic,,,but that thing makes u feel like ur in a cockpit,,,less convenient no doubt...but fits in my defenition of 'cool'...
lol

the bottom line: its NOT worth the time, money and effort to do a manual to auto climate control conversion. at least you have some sort of climate control. its not like youre gonna wanna have the climate at a steady 73 degrees.

If you have the 'stock air conditioning and heating with the sliding bar...' then you do have climate control.
(all Maximas have climate control)

Uh, yes it is "like youre gonna wanna have the climate at a steady 73 degrees.". That's the beauty of automatic climate control.

Hahaha that's a great pic! It looks like you photoshopped a normal pic. (I'm not saying it's not real, it just looks out of the ordinary.) Awesome!

These are the instructions for converting the manual to automatic climate control for a 98 (my apologies - I am not able to post attachments yet):
New climate control components required (from a 1998-1999 Maxima): Control unit (w/in-vehicle sensor) with M97 and M98 connectors, air mix door motor actuator with M113 connector, mode door motor actuator with M112 connector, fan control amplifier with M57 connector, sunload sensor with M64 connector, intake sensor with M54 connector, ambient sensor (E28 connector should be pre-wired but may be difficult to trace wires so may be easier to run new wires).
Note: You will need a copy of the FSM manual pages HA-90 thru HA-93 for the auto climate control wiring diagram and pages HA-39 thru HA-43 for the manual climate control wiring diagram - the terminal numbers provided are explained on those pages. You can either ‘tap’ into the existing wires of the M39, M85 and M86 connector terminals for the connections to the new wires of the M97 and M98 connectors or cut the M39, M85 and M86 existing wires near the connectors for the connections to the new wires of the M97 and M98 connectors.
Disconnect the negative terminal at the battery.
1) Remove the existing mode door motor actuator (located on the driver's side on the heater assembly behind the radio/climate control), install the new mode door motor actuator.
2) Remove the existing air mix door motor actuator (located under the heater assembly behind the ECU), install the new air mix door motor actuator.
3) Connect the air mix and mode door motor actuator wires in parallel (3 wires color codes L/W, L/B and B), run the 3 wires to the to the climate control unit location.
4) Install the ambient sensor (located behind the Nissan grille near the horns), use existing wires or run new wires to the climate control unit location.
5) Install the sunload sensor (located on the passenger side defroster grille), run 2 wires to the climate control unit location.
6) Install the intake sensor (located at the face of the evaporator coil), run 2 wires to the climate control unit location.
7) Install the fan control amplifier (located on the blower assembly to the left of the blower behind the glove box), run ground wire (color code B) back to the climate control unit location. Disconnect the existing fan resistor connector M77 and pull the connector as close as possible to the fan control amplifier location. Connect the fan control amplifier connector M57 terminal 1 (color code L/W) to the M77 connector terminal 1 (color code L/W). Connect the M57 terminal 2 (color code L/Y) to the M77 terminal 3 (color code L/Y).
8) With the auto climate control connectors M97 and M98, the manual climate control connectors M38, M85 and M86 and the new wires at hand:
Connect the color code L/W wire of the air mix and mode door connectors to terminal 21 of M97, connect the color code L/B wire of the air mix and mode door connectors to terminal 16 of M98. Connect the color code B wire of the air mix and mode door connectors and the fan control amplifier, to terminal 32 of M97 and terminal 17 of M85 (color code B).
Connect the terminal 27 of M97 to terminal 14 of M85 (color code LG/B).
Connect the terminal 24 of M97 to terminal 15 of M85 (color code L/Y).
Connect the terminal 25 of M97 to terminal 16 of M85 (color code R/Y).
Connect the terminal 2 of M98 to the wire color code OR/B of the ambient sensor (terminal 1 of E28), connect the terminal 12 of M98 to the wire color code OR of the sunload sensor (terminal 1 of M64), connect the terminal 3 of M98 to the wire color code OR/L of the in-vehicle sensor (terminal 1 of M41), connect the terminal 1 of M98 to the wire color code R/W of the intake sensor (terminal 1 of M54) and connect all the wire color codes B/Y of the sensors (all terminal 2) to the terminal 11 of M98.
Connect the terminal 8 of M98 to terminal 10 of M86 (color code R), connect the terminal 18 of M98 to terminal 9 of M86 (color code Y/B), connect the terminal 19 of M98 to terminals 21 (color code Y) and 24 (color code G/R), connect the terminal 28 of M97 to terminal 20 of M85 (color code L) and connect the terminal 36 of M97 to terminal 11 of M85 (color code G/B).
Connect the terminal 13 of M98 to the terminal 28 of M85 (color code L/B).
Run a wire from the blower motor connect M76 terminal 1 (color code BR/W) for a connection to terminal 33 of M97.
Connect terminal 35 of M97 to the terminal 3 of M39 (color code L/Y).
Connect terminal 34 of M97 to the terminal 1 of M39 (color code L/W).
Connect terminal 22 of M97 to the terminal 13 of M86 (color code LG/R).
Run a wire from the fuse 40 (fused side which would be the right side if facing the fuse box panel) to the terminal 26 of M97.
Re-verify all connections. Plug in the M97 and M98 connectors to the auto climate control unit.
Re-connect the negative terminal of the battery.
Turn the car on and test the auto climate control unit AUTO function (temperature setting to automatically control heat and A/C functions) and manual function (defrost, vent, floor/vent, floor and blower speed control). There are a series of built in functional tests that can be done with the auto climate control – refer to the FSM section HA pages 70 thru 77.

wow. Big project. I have a auto climate control and it's not a big thing. I'd have the regular climate control if that's what my car came with.
One thing I dont like about the auto climate control is that if you press AUTO it runs the AC no matter what temperature you select. Even if you select 80 degrees it will run the AC and the heat simultaneously so the air is 80 degrees instead of just using regular air and the AC when needed. Just a waste of fuel unless you press econ.
Also whenever you press a button (Auto or Econ) it automatically goes to the highest fan setting and you get blasted.
Its not the best thing since sliced bread and in my opinion, not worth this much work.

I actually found that if you take out/or just blow with compressed air the thermistor located on the face of the acc it is a lot more accurate, it gets loaded up with dust and such which acts as an insulator.
