2001 GMC Jimmy 6 cyl Two Wheel Drive Automatic 72000 miles
I have a 2001 gmc jimmy and a few days ago I noticed a burning odor inside the truck when I'm driving. I also noticed that a small amt of smoke seeping from vent located under the windshield. I was told it could be the heater core going out. If this is the problem how much does the part cost and could I get someone to put it on for me and would it be difficult for them to do so. Also, I'm still driving in short distances but will this make the situation worse?
