Anyone know which servo controls the heater control valve? Heater is only blowing out cold air... (2GS)

I'm cold !

 

Heat Servo Motor Original part # 87160-30371. Check on eBay. I buy for $115.00 and is located on the left side when you take out the glove compartment. The first one close to outside. Search on ebay, item # 251576123110. Also, if you call your local dealer he can send you a fax picture that where is located this heat servo motor.

 

I have a servo from toyota that came with the car which might be it, i'll check the parts number when i get home. So it sounds like its easy to replace...

thanks a lot man!

 

U are welcome. Also, the servo is more close to the Radio when U take the glove box out and the CD player out. U want a see a wire harness that pass on front of the servo and you left side. Take that wire out the way, have a plastic clip, just take it out from the base of that plastic clip. Look very well that is easy to move that plastic clip and the servo have 3 screws. The more difficult of this 3 screws is the one that go far a way pointing to the fire wall on the bottom. Flexible screwdriver or small screwdriver help U a lot. Take me like 30 min. to do it and I do it very slowly. I take my time to do it. Very import test that servo before put back the wire harness clip on the base, the cd and glove box. For U to be sure U installed it correctly. Try to install the servo on the 2 pin on cool position. The servo have one pin and on the other part of the box AC compartment have the other pin. Try like I say to mach this 2 pin on the position that need to be. If U putting wrong the pin that is in the system and not on the servo, your 2 center windows not blow any air. That is the reason that U need to test before put everything back and good luck

Mode Servo.

 

Ok so i had everything off and was looking at this servo...it seemed to be in working order....it switched to every position. In fact it seemed that all 3 servo's were working.

However when i turned the heat on it was blowing semi warm air! (which could have been enough if the mornings weren't so cold.) The two coolant pipes going in and out of the heater core were hot/warm which led me to believe that the valve was operating as it should?

The air becomes colder after a while tho and it seems that it happens when im driving.

Any ideas?
