Question about 2005 GMC Envoy
A few weeks ago the fan would not come on for the heat. Then just as suddenly it started working again. Now this week a smell when heat is turned on. No water on floor, no fogging of the windows and not real sure if the smell is antifreeze or like a burnt motor electrical smell.
Any ideas? I am thinking of running AC to see if I can still get odor. But will this eliminate the heater core as possible issue.
Only reason I am thinking motor and not heater core is the fact about it not working and then working again.
Any idea what kind of job blower motor or heater core are on these cars? (whole dash out?)
Vehicle has 39,000 miles V6 ext.
Sounds like your blower motor , you heater core is a non mechanical part and if it were the issue you are correct in thinking you would see fluid on the floor or mist on the windshield.
