Hey, I have an interesting problem I was hoping someone here could help me with. If the fan is blowing hot air, and I turn the **** to cold, it will still blow hot. The only way to make it blow cold is to turn the other **** to defrost and back to whatever setting. Then it's stuck on cold. In order to make it blow hot again, I have to turn it back to defrost and back.

 

I have the same exact problem! I posted about it and one person's reply was the wires are no longer soldered together correctly. Just pop the dash off and you can look behind the ***** at the white connector. I hope this helps I still haven't looked at mine yet.

 

This could also possibly be a bad Blower Motor Resistor. Check that as well.

 

I would love to hear that Explanation.....


Anyway......You have a classic case of Broken Door Syndrome. The Pivot Develops a crack, and the motor "Over travels"...The only way to bring it back is to reverse direction.....

Technically, It really has Nothing to do with HOT/COLD....but rather the Overlap of the mode doors...Typically, Atleast from the ones Ive seen...its the defroster door that causes all the issues.

Now the bad news, Remove the dash , remove the heater box, dissassemble it, and find your broken door.

No other way around it.
