ford truck

8 posts in this topic

Well my truck is getting a little tired and she's starting to act up a bit. My temp is stuck on hot and no fuses are blown. Any ideas, I thought it's probably the climate control module, but don't know how to test it.

Some detais here would be helpfull. Year, make, model, does it have EATC?

More then likely the blend door motor went bad, or something is stuck in there.

It stands for electronic automatic temp control, dou you have push button, or knobs to adjust your heater?

If it is always blowing hot air, then it will be one of a few things. The switch that controls the temp, the actuator that moves the blend door (blend door motor), wires in between them, or a stuck blend door. Most comon would be the blend door motor bad.

It looks as though fuse though fuse #5 feeds power to it. When you turn the blower on position 2, and turn the temp from cold to hot, back to cold, can you hear a change in the sound of the blower?

knobs that turn.

4WE pretty much covered all the regular items. I have also seen it when the black knob for the temp/blend control cracks on the backside and does not spin the metal stub sticking out from the temp control head. You can pull the knob off and check for a crack or spin the metal stub with a pliers.

Worse case would be a cracked plenum (heater box), causing the door not to move.
