Question about 2003 Mercury Grand Marquis
I need the code and the method of input for my 2003 Mercury Marquis climate control to manually move the blend door. At the moment I only get cool or cold air even when the temperature calls for heat.
I have checked every site that I can think of and run the question many times, unable to get the procedure, maybe a nice tech at the local dealer will help u out, if not I guess buying a service manual might be your only option. I am a retired Ford mechanic, I did almost all the AC work, I never found this problem was a control head issue, it was always the blend door electric motor, I think you can see it from the glove box if you remove the liner.
