    Question 1993 GMC Jimmy 4WD A/C Heater Core

    Your manual 24070 (831) "Chevrolet & GMC S-10 & S-15 Pick-ups 1982 thru 1993" in section 3, item 10 "Heater Core - removal and installation" makes no mention of having to loosen/remove the dash to get access to the heater core and it's duct cover. I've just tried to remove the duct cover over the heater core, but there's no way I can find to wiggle or force the cover off and down past the heater core. It seems to be blocked by the dash - mostly by the glove box. Do I need to pull or loosen the dash?

    Hi kmurph38,

    Email one of our tech service reps at [email]research@haynes.com[/email]. Let them know what's going on (again, sorry), what book you're using, and give them the number/letter combination on the title page, just to the right of the Haynes logo. They'll do what they can to help.
