Hi, I'm wondering if anyone could help me out or give me a guide to fix my heating issues in my truck...I'm wondering if I need to replace the heater core or maybe just the thermostat?
The fan works when I start my truck. but it just blows out nuke warm like air...its not cold, or its not hot..If anyone could tell me what to do or help me out with some info, it would be greatly appreciated

 

Yes it could be the thermostat. That is a place to start. I had the same issue with my F-250 and that was the culprit.

 

Alright thanks Bill...I'll try replacing the thermostat and see if that works...I'm hoping that will be the problem...I live in Saskatchewan...and out winters are cold...so i need my heat!!
