I drove to work and the heater and gauge worked fine. 8 hours later on the drive home i noticed the temp gauge wasn't moving. And there was no hot air. The temp gauge just sits right on the very first mark which i believe is 130.

Is this a stuck open T stat? or something else?

 

I'm thinking your correct with the stuck T-stat. It wouldn't allow your engine to warm up, and of course no warm engine, no warm coolant, no warm heater core, no heat...

Should be an easy fix for you though.

 

If not the tstat, then there may still be air in the system. It can be a real PITA to get it all burped out!

 

bad t-stat. replace.

 

I forgot i had installed a fail safe. What a piece of crap. I just removed the fail safe part of the t stat and re installed.
