Hey guys, Ive searched and not found really anything but people talking about their heaters. My problem is when the a/c is on cold or heat there is no air coming out of the vents, the blower motor does not turn on and the a/c clutch does not engage. I tested both of these (blower and a/c clutch) and they both work as well as I verified the circuit breaker was getting power... I check to see if the blower motor was getting power and it of course wasnt. I checked the a/c fuse and it was good, BUT I noticed that there was no power going to either side of the fuse...??... The a/c controller thing works find and everything lights up and acts like its working... I read about the coils but I was under the impression they would only keep the low settings from working..... SO can someone please give me some suggestion.....

On the page I linked to, it shows the heater relay, which powers the blower motor. I was just trying to show you the direction, since you indicated you were going to do it yourself, and not pay a proffessional.

Good luck.

after alot of what seems to be unnecessary testing now, found the problem to be heater relay. Granted it was fun taking everything a part. HOWEVER, Now when the car first starts and the a/c runs for like 30 seconds, it stops work. Not only the blower but the compressor also. I comfirmed its not the compressor causing it by energizing it myself and it ran fine. So this takes me back to the relay might be f'd up. I got it brand new from NAPA, yall think it could be that or is there something else I should be testing for?

Could try one from a junkyard?

Also if it's low on gas it will shut off so that's another thing to check.

you mean if its low on freon?? or like if its low on fuel? I am assuming you meant freon, but I tried putting in freon while it was on but it didnt come back to life so Im guessing thats the problem, but I dunno

I come from a land down under
Yep Gas=freon in this case sorry!
(Here "gas" is either LPG or any other gaseous substance your Gas is our Petrol)

Do you know anyone else with a Supra?

If so borrow their Amplifier box and see if it fixes it.

I have the manual infront of me and will go through the diagnostics of the amplifier to see if its functioning properly tomorrow and will poast the results...

it is weird though, the blower will work if the car is in the on position (and not started), and will work for like 30 or so seconds while the car is running, but then the compressor clutch and the fan just quit working

well assuming its the same part ('87 mines a '91) and you give me a price and compare it to something since I have no idea how much one costs new or used. then maybe you have a deal, of course this is all assuming that it is infact my problem...... but will advise tomorrow.
