Have read tons of these posts and have my glove box all apart after having cold air blowing. Traced it down to Hot/cold servo (may not be correct). Tried to clean and nothing. When I did hook it up to test, the arm only went to one spot regardless of heat control position. Bit the bullet and ordered new airmix servo from dealer and installed, connected harness and "NOTHING".

Saw a post about removing the ECU-B fuse so I did and went to try heat and it moved like it should. I was very happy. Went inside for about 1 hour, came out to put back together and Nothing!!!!

Yes I tried fuse again!!

The servo doesn't seem to be getting correct signal or NO signal...


Any ideas?? What next?

 

Just a thought ..

Try warming the engine a bit. The fan does not kick in till the coolant gets a bit warm, maybe the the servo also waits.

Does anyone know how to test at the servo itself to see if it's getting a signal/voltage etc. I am assuming that if I have a brand new servo and it still isnt working, then its not getting a signal..

 

may I know the OEM part Number for the air mixed servo ?

thanks,
Mike
