no air condition fan, no heater fan on 89 camry - Toyota Nation Forum : Toyota Car and Truck Forums

bayawan · 10-01-2009, 12:02 PM

I have a !989 Camry le v6 auto trans 168,000 miles
Several months ago the air condition and heater were working then out of the blue they just stopped. The next day it came back on, then a little while later while driving it stopped again, like it had a short. It did this on & off for several weeks now it doesn't come on at all. We can't find any shorts anywhere.
The little green button control lights do work.
The blower fan does not work.

One repair shop said the circuit board in the dash behind the controls was bad but Toyota says the circuit boards rarely go bad.

All the fuses are OK. The circuit board did not have any burn or dark spots.
Are there any hidden fuses?

There shouldn't be any hidden fuses, but you could also be having a relay problem. From the looks of things on the diagrams, it could be the Heater Relay which powers both the blower motor and A/C system. It should be located in the passenger footwell. There is also a 40A circuit breaker next to it that could also be the problem.

Check those out and see what you can find.

Have you tried the blower on the highest speed? Many times the blower motor resistor goes bad and only the high speed works. It can also be the blower motor itself. Remove the electrical connector and apply 12 volts directly to the blower. If it doesn't spin, the blower motor itself is bad.

If it was just the blower motor resistor, the A/C light would still work... though no air would flow unless the 'high' speed was selected or the car was moving an the fresh air mode was selected.

Thanks for the input.

This morning the the air condition and blower came on for about 5 minutes then just shut off without warning. While it was on I could switch between high speed and low speed. It would seem there is a short somewhere that shuts down the heater and air condition system (including the compressor) but doesn't shut down anything else.

Charlie you mentioned something about the A/C light not being on..

well i had left my driver side window down overnight and it had rained all night.. so my seat was wet and the entire driverside door. well my A/C had worked on HIGH and I think LOW but that's it (i know that's the blower motor resistor..just haven't found a good one yet) .. but now my A/C isn't working, and the A/C light isn't lighting up now.. it was really humid in the car too... should I check fuses? aren't there two fuse boxes in the 90 camry? Thanks in advance

There are fuses both in the engine bay and in the driver's side kick panel. There are also a few relays 'n stuff in other places around the car - some A/C related stuff is under the passenger footwell kick panel (opposite where the main interior fuse box is).

Does the A/C light flash at all, or does it never come on?

It does sound like there is a short somewhere in the system. My guess is the blower motor... see if you can get a cheap one from the junkyard and replace it. They are pretty easy to replace (just a few screws from the bottom, if I remember right).

i went out and cut on the A/C .. and it was back to "normal" .. still only worked on high and medium.. but it worked.. i guess the humidity in the car kept it from working? hmm.. quick side question.. I pulled a blower motor resistor from a 90 camry.. and it didn't fit mine.. the plug was a different shape... i have a feeling that maybe it was a different model of A/C? honestly i don't remember what it had.. but i guess that's the answer. what do you think?

The blower motor... , maybe somethings wrong with it, you can replace it to the result. Good luck.

This might sound like a stupid question but where is the blower motor?
Is it in back of the air cond-heater controls, inside the dash?

Mike Gerber · 10-07-2009, 11:27 AM

It's on the passenger side of the car up and under the dash near the kick panel. You might have to remove a few things to get to it. Then to remove it it's usually just an electrical connector and 3 nuts holding it in.

Its right behind the glove compartment. You may be able to replace it by just removing the lower trim panel (black piece), but I'm not sure. For sure you can do it after removing the complete lower dash panel which is easy if you know where all the fasteners are...
