Question about 1991 Chevrolet C/K 2500
When I turn the heat on smoke comes thru the vents. It fogs up the windshield and smells horrible. Do you think its the heater core. And how do you change it. 1991 Chevy GMC Conversion van
A good friend of mine taught me his trick , Take a jigsaw and saw off the top of the box mounted on the firewall then yank it out and replace it use black duct tape to replace the part you cut out, Screw the dashboard routene, All you need is heat the core costs 40.00
