Optional Information: 1996 GMC jimmy 4.3l
First of all does the engine get to operating temperature on the gauge?
Do the heater core hoses both feel the same hot temperature?
yes, reaches normal temp..and yes hoses seem to both be really hot.
Do all other functions work? Are you able to change the blower speed and the location where the air blow out?
yes .i can change location of blowing.and it works normally..just no heat
Ok, this sounds like a problem with the HVAC controls or the temperature door. Verify that the temperature door is moving when commanded to different temperatures. If it is not then we will need to check the controls.
I.m not sure where temp door is located..it is now running ..are ya still there? Been an hour I'm not sure if I lost you or your major busy..should I try a new question??????39460.8204512384
