My A/C does not blow cold air. Compressor is okay, freon is okay, all under-hood wiring, switches, and relays have been checked. All the places I have taken it to say that there is something wrong in the dash.

I took the dash completely apart. But I cannot make out the A/C parts from all the others to see if something was disconnected.

All help would be greatly appreciated.

 

It looks like to me you need to let the places you took it to let them fix it. If you had people look at it y didn't you get them to fix it instead of taking apart all the stuff you did?

 

I had the same problem, only it was the hose from th compressor to the firewall. I bet thats what it is with your car as well. All maximas seem to have that problem.

 

All the places I took it were stumped. They were all unwilling to go into the dash, that's why I did. The dealership wants $150 to tell me what is wrong.

 

The compressor does not come on when you push the button, but it will come on if bypassed. All the pressure and electrical switches under the hood have been checked, and a 5-hour vacuum leak test was performed.

 

What pressure reading did they get when they got the
compressor to run low side should be around 30-40psi
high side should be around 90-110psi. if the readings
are unequal (one is ok one is not) then we have problems
if both are low needs refrigerant if both are high to
much refrigerant or to much oil.

 

Hey Maximum5spd:

Could you elaborate on what the problem was with your high pressure hose (from compressor to firewall) ?
Was it plugged? Kinked?

Thanks!

They did not test that. They tested the components individually (electrically, and with the system pressured up), but they did not get the compressor to come on. The compressor only came on when that wired it directly to the battery through a separate fused circuit. But they did not test it while it ran, they just bypassed the switches and turn it on for a second to see if it was working.

The first place I went to did what is listed above. The next place tested the compressor, the evaporator core, the condensor, the high side, the low side, and everything was okay.

The next place was more in-depth. They had one of those audible volt meters and checked all the under the hood wiring. It was okay, but no one has checked in the dash, and that is where that all say that the problem lies. The first 2 places can't even fix it, the third has offered to bypass the installed switches and relays with a custom switch to turn the system on.

He wants $500 to do that.

 

The hose it self had holes ant freon kept coming out if it, bubble by bubble. Untill it all leaked out.

 

Hey Max5spd - what is the story behind your tail lights?

(sorry to go off the A/C topic)

Back to the topic...the $150 the dealership charges is for 2 hours ($75 an hour). This is then absorbed into the total cost should you let them fix the mother flocker. Another two/three hours labor to the total?
I guess my point is, at $150 you at least know for sure what is wrong. At that point you can walk away with a hundered fifty dollars of air condition lessons and fix it yourself, or let Nissan fix it properly. Either way, you don't **** yourself around with joe mechanic telling you he's going to rewire your car improperly for $500. Nissan can do it for that price and do it right at least, and hopefully cheaper. Regardless, for $150 they'll tell you upfront what it's going to cost. And from what your describing, it's labor time, not expensive parts that need to be replaced.

When you've had this many opinions about your car and you're still no further ahead, sometimes it's best to let the guys who work on your particular car every day do what they do best - and do it right.

May your ***** not fry this summer!

My apologies for not being to offer any technical advice into the mix on this one. Just think of me as the camp counselor.

I meant opinions from the shops you took it to. Not the opinions of your Maxima.org family

 

I wanted my tails to look like the R33.

 

I like them . I just wanted to know what they're called. How you came by them, etc. Never seen something like that avail for the 3rd gen.

 

I did everything my self. With some help from a shop.

 

OKAY...I went to the dealership (Bankston Nissan in Irving). The service manager James took one look at my car, and pointed to the ambient temperature switch (located between the grill and radiator). He has a '91 SE as well, and said that the switch is unecessary, but often goes out and will cause the compressor not to kick in. He by looped his and did not even replace it.

It turned out to be a loose connector on mine. It maybe a short, but he wiggled the connector, and the AC kicked in.

He didn't even charge me. How cool is that. I told him about Maxima.org, and he said he'd check it out.

Looks like I'll keep all genitalia of the skillet this summer.

 

Had a feeling a trip to the dealer would help put things in perspective. Obviously, the dealer isn't the first place to run to normally, but it just sounded like these other clowns were more interested in your money than actually telling you what was wrong with your car.

Good Stuff!!

 

Ahh you have auto a/c wish i'd have known sorry I
couldn't be of more help.
