Heater Issue

My heater stays running with the ignition turned off. The blower runs at any set speed even with the key offf and out of the ignition.

Sounds like a relay stuck. It should say which one it is in the owners manual or a chilitons. You could swap out another relay to check but I have had that happen before.

Today when i got home from work and shut hte truck down I could hear relays behind the dash in the middle clicking. I wonder if I have the leaking windshield wows.

Mine did the same thing when it rained. I read that the windshield leaks into the GEM module and that caused my blower motor to run. It dried out on its own and had the windshield leak fixed.
