So I tried searching the forum but my browser kept changing to "websearch....etc" and stopped. So I couldn't look up my issue.

But here is my issue: A/C compressor works fine (line gets wet and very cold) inside the car though, no air blows. When I turn the A/C button off and press the vent button (not eco.) where it controls where the air flows. Air does come through the vents. Any idea on what this could be?? All my fuses are good.

 

do the lights come on on the buttons when pushed in?

 

Yes, all the lights work, defrost as well.

 

so the fan selector works (off to high) and all the vent selections function properly EXCEPT when the a/c is manually turned on, and all fuses are good? if all that is correct I would think it's a problem in the control panel.

 

^^^+1

 

Have I seen you around town before? I have a green one with a huge dent in the back..lol

Anyways, I def not a noob to this car, but where is the control panel located? I'm thinking I prolly call it something else...haha

 

the actual part with all the a/c controls on it. fan selector, defrost, etc. the one you're messing with.

 

carefully remove the shifter bezel, it's held in by clips. at the bottom of the radio/ac bezel there will be 2 screws. take those out and I believe the top is clipped in. once that's removed the a/c control panel has 4 screws holding it in. take those out and check the backside for good connections before unplugging everything. ya might get lucky and not have to replace the whole thing. if there appears to be a burnt spot, there's your problem.

 

Hmm, ok I'll take a look at it. I almost did last night but ran out of time.

Thanks guys for the input.

If anything else comes to mind, obviously feel free to post

 

Yeah, I've removed it several times for my head unit. It takes about a minute to do

 

yeah it doesn't take long and no problem, it's fixing to get hot down here lol

 

Auto Climate control uses an "amplifirer" to control fan speed.
You either have a bad amplifier board or a defective blower motor.

 

the fan speeds to auto control while no air is blowing. Blower fuses are good though? Are they for something else?

 

can you hear the blower motor run even when it's not blowing out of the vents? or do you hear it just when it comes out of the vents? not sure how the auto climate unit works, was thinking you had the manual type.

 

No I don't where is that even located

 

Passenger foot well in back of the glove box. If the motor will not run you either have a bad amplifier or defective blower motor.

 

if you turn the fan on the highest speed you should be able to hear it from the drivers seat. it's the humming noise. sounds like a fan cuz that's basically what it is.

 

just a question... if you do have the auto climate control, can you still manually run the a/c or does it have to be run by the auto climate feature?

 

'Passenger foot well in back of the glove box. If the motor will not run you either have a bad amplifier or defective blower motor.'

he did say the vents blew air so wouldn't think that it's the blower motor. it will work or it won't not when it wants to.

 

had this happen to me before, i tapped my blower motor and it worked fine forever, also recharging ac could fix it. but it could be a burned wire to blower motor. i had to mess with mine to get it to work right.

 

i'm thinking it's the blower motor, control panel is fine. Is the blower motor the one with the cabin filter? I got most of it apart yesterday.

 

didn't you previously say the vent mode blew air out while the car is parked? if that's the case it sounds like it works to me.
not sure about the filter but it is located behind the glove box/kick panel.

 

No it doesn't. When i'm driving the outside air comes in.

 

oh ok I misunderstood what you said in the original post. yes it should be the blower motor if all the fuses and relays are good. you can try to 'direct wire' it to see if it works for sure.

 

Ok 3rd and last time. It's either your blower motor OR the amplifier (blower speed control for auto CC). You need to troubleshoot. Test the motor, check resistance as per the FSM. If it passes, your amplifier board is the cause.

The blower in auto cc hvac works differently then a standard blower with a resistor pack speed control.

 

Ok so I'm replacing the blower motor on my car, But I have to splice the wires to the new one (way to go autozone) but there is a blue and brown wire. Which is pos and neg?

 

nothing

 

Ok so it doesn't seem like it the blower that the problem is, where is the resistor located?

 

Ok, so I tried to do the voltage test on the wires for the blower motor, nothing. The guy from autozone said either loose wiring? or a bad relay? Can anybody input on this? The blower itself works cause I tested it on the battery.

 

with the ignition key on and the fan speed on check use a test light or voltage meter check the voltage at the blower motor electrical connector. if the motor is recieving voltage but not operating, either the motor ground is bad (blower switch and resistor are part of the ground circut) or the motor itself is bad.
to check for a bad ground, disconect the electrical connector from the motor, connect a jumper wire between the ground wire terminal on the blower motor and a known good ground.then connect a fused jumper wire between the batterys positive terminal and the positive terminal on the blower motor. if the motor now operates the ground circut or resistor is bad.if the motor doesnt work the blower is bad.
if the ground circut to the motor is bad check the blower motor resistor. the resistor is just below the motor. using an ohmmeter check for continuity to ground at the resistor electrical connector while the blower switch is rotated through all switch positions. continuity to ground should be present at all three of the terminals in all of the switch positions except 'off'.
if a ground signal does not exist at the blower resistor connector repair the blower motor switch and/or the circuit leading to the switch.
if a ground signal from the switch does exist at the blower resistor connector, check the blower resistor for continuity between the terminals. if any checks indicate infinite resistance replace the blower resistor.
also should check the continuity of the blower speed switch.

a chilton repair manual specifically for these cars is very helpful and will have pics and wiring diagrams and will include all of this information. can get it at the local parts store.

problem is bad ground!! Yay, I'm tired of messing with this. Now since I don't feel like tearing my dash apart to find where the wire goes bad or is loose, can I run the ground to another wire? My resistor (which I'm assuming works) is way different than what autozone or oreilys has to sell. I'm assuming cause it's auto A/C.

 

Ok, so I spliced the red one with orange wire, and the black one on the blower motor with a black ground that went to the glove compartment, now as soon as the key is in the on position, the motor blows hard, but at one speed, any idea?
