• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

2005 grand prix-3800 not heating up, temperature gage goes up to normal blower works fine. checked hoses and they are rock hard and fan does not come on. what could be the cause?
 


DEX Cool possibly has clogged up ur Heater Core. Try removing to hoses to/from heater core and run water through it. See if it's blocked. I would start there. IMO
