So this is my first time posting on here. I've been looking around for a couple weeks now since I just bought a 2001 Bonneville SSEi and been getting everything fixed up.

So my first question is, my headliner on the sunroof slider thing lol (sorry don't know what that thing is called) is falling down and I want to fix it. Is it possible to get that thing out of there to fix it corrected or is it a big deal to get it out?

Next question is about the A/C. The driver side A/C is not as cold as the passenger side. Its very noticible and I'm not sure what to do about it. Both temperature are set the same and the mode is set the same but you can put you hand in front of one side then the other and there is a big difference. The passenger side is much colder.

Thanks for all the great threads and thanks in advance for this information.

To get the sun roof shae out, you need to pull the headliner out. I was able to glue down the front areas on my shade that were coming apart, with some rubber cement.

The problem with one side being colder/warmer than the other is probably your mix actuator. Here'* one thread on the subject https://www.gmforum.com/t280678/

Use the forums search feature and look for more info on heater and ac.

also, please add your year and trim of your vehicle to your signature line. That way when you start asking questions in other areas of the forum, we all have a better idea on how to assist you. Click on "Quick Links" above, go down to "User Control Panel" and then click on "Edit your Signature" It'* pretty straight forward from there.

you can get the sun shade out through roof opening. take off defector, remove glass (4 torx bolts) slide shade forward depress 4 tabs. itll take all of 15 mins... DONT PULL THE HEADLINER! so much more work that is not needed.

Dan is correcto mundo, removing the headliner is a MUCH more involved procedure. Here'* a diagram depicting all of the relevant bolts/screws that you'll have to remove. It'* shows the exterior of a Buick for some odd reason, but it'* taken from a '01 Bonneville parts listing:

Try adding refridgerant to A/C system to fix warm driver side air. That was my issue last time.

+1 on removing sunshade through the roof opening.

you dont want to add ref. without knowing what the pressure is. i would look at the pressure and if its low add some
