I think you should start your own thread, but separate the issues into different posts. Post details of your problems and pictures, and don't ask for people to communicate with you privately. One of the great things about this forum is that you can look up where other people have had the same or similar problems, and read the answers.Jasen,
I have rear heat and air, but nothing up front. I know the post I'm replying to is 4 years old, but I need assistance in fixing my issue with HVAC. If you have pics related to this fix please send them. Also, I'm tackling the door handles and door puns and bushings. Pics would help there as well. 2001 GMC Safari 2WD LT. Please feel free to email me at bryanmuse@gmail.com. Please put Astrosafari as email heading so that I know who/what it is. Thanks!
Did you replace any of them or just reconnect?Yes, you’re correct. Thanks! I got all the hoses hooked up and it all was working for a day or two but it’s back to only coming out of the defrost vent again. Now I’m thinking I might need to replace that canister, assuming all the hoses are still connected.
