1999 GMC Jimmy starts blowing out hot air in the first 5 minutes running and then will not be cold at all. Seen information that the blend door or acuator is stuck or not working properly. How do I get to the blend door and/or actuator? no cold air is coming out and its charged
No, you just need to fill freon gas.

1999 blazer,only getting heat from a/c- coolent is fine ,compressor working,bi-level controls work fine ,blend door is working behind glove box,the lines under hood are cold. Is there another doorway that could be closed and not letting the cool air through under the dash? I can feel the cool air when I got behind the glove box and ran my hand towards the firewall ( not blowing, but enough to know the a/c is working to that point)
Where can I get a detailed diagram of my ductwork/dashboard. please help
