Hey guys, I have a flashing temperature on the auto climate control head unit. It goes away after about 1 minute of operation. Here’s a vid: All vent modes work fine (I replaced the vacuum lines behind the glove box like this guy did ) I did notice the passenger temp control on the door...

Hi all, I’ve been running the air conditioning on Max AC I’ve noticed condensation building up on the outside windshield. It looks like some of the cold air is directed through the windshield vents and not fully through the mid vents causing that part of the windshield to get cold and build...

A month ago when I got the car, the a/c was blowing at a slower than usual rate. We replaced the blower motor resistor and that seemed to fix it, the fan was back up to correct speed. Then after 3-4 trips, the a/c shut off completely (nothing coming from fans at all). We replaced the a/c control...

Has anyone encountered a hissing sound in their TourX from the dashboard? It sounds like some type of pressure relief. It tends to do it the most/sound the loudest when I first turn the car on. It happens when I drive too and has been getting a bit more frequent. At first I thought it was the...

I replaced the blend door actuator but the temp blend still does not work . When operating the blend controls the rotator in the new actuator does not appear to be moving. All other doors seem to be operating correctly. If the cause is not the actuator any suggestions on the next most probable...

I have a 93 Lesabre Limited with Dual Zone climate controls (CJ2) [Climate control head C1] The heater core leaked into my HVAC programmer and fried it so I started hunting around but they're almost impossible to find. I was unable to find any programmers with the same model number as my...

I’ve searched the Internet and YouTube and familiarized myself somewhat with the terrain of this issue. I’ve also spent a lot of time going through this forum and reading what threads I could find on this topic before giving it a go and making this post. I wasn't sure if I should append this to...

Hey all, I have a 2009 Lucerne that I have been taking care of for a while. This site has been a ton of help so far, but this issue is one that I cant seem to figure out. On long drives (1.5 hr+) I usually set the temp to 72 F and set it to auto. What has been happening is that after a while I...

Hello, I have recently replaced the coolant elbows going through the idler assembly acouple days ago. I have removed all air (or so i think) out of the system. My issue is that I have very little to no heat comming from the vents when the temp is set to max and the engine is at operating...

Compressor kicks on and off, pressure on AC Pro was right, ac pro only checks high pressure side though I believe... It has manual dual zone controls, which I already replaced (with a used unit) The heat is super hot, but when it's on max ac it still feels a little warm, and having AC on or off...

Hi, I have a 1999 LeSabre limited with dual, automatic climate control. The "Air Flow" button doesn't change the air distribution, and it only comes out of the drivers vents, with a small amount coming out of the passengers vents. I've done my research, and from what I can tell, it's the AC...

The air stopped working on my 05 lacrosse and I saw the 30A BATT MAIN 4 j-case fuse was bad. I replaced the fuse and the car immediately started blowing electrical smelling smoke out of the vents and the fuse blew again. What would be the next thing to diagnose from here? Is it possible that...

Hello all I am having a problem with the digital climate control system on my 93 Roadmaster. The vents are stuck on the upper section, which I know can be a blend door issue, some air comes out at the floor, but not a lot. I am starting to believe my module is faulty. When I try to turn on the...

Hey guys, my main problem that made me start the job was no heat. I’ve got heavy condensation buildup on the inside of the windows, a little rust under the dash. Naturally i thought I had a leaky heater core ( I also had water pooling in rear passenger floorboard, and park on a slight incline)...

Hi, all! Just discovered this forum. I've a host of issues that I hope y'all can help me with, but this is the most important one, so I'll start here. Car: 1999 Regal LS, just turned 100,000 miles (!). Engine, drive train reliable, but anything to do with the body, total crap. Me: Been...

So I went to recharge my girlfriends A/C and it became apparent that there is a leak somewhere. It is a 99 century custom... any idea on where to start and/or common issues with this car's A/C???

I have a 2004 Buick Lesabre Limited, how do I remove the dash bezel so that I can remove/replace the HVAC module/control panel? Thanks.......................Bill

Hello, I'm new here and to Buick, nice to meet all of you. My partner was driving around one day in Sacramento with the AC on, then stopped for lunch, and after coming back the HVAC fan is suddenly running very poorly. The fan is working, and responds to commands to change fan speed, but the...

Greetings from the northeast! Just like the title says, I've got a 93 roadmaster wagon and it's gotten a bit cold so I thought I'd finally fix the heat. I have the FSM and it looks like I need to replace the air blend actuator. Seems common on the electronic HVAC systems. I bought a...

Does anybody know which fuse is responsible for the backlight LEDs on my ComforTemp HVAC control unit? Think I shorted something out when installing a new stereo and now none of the green LEDs are lighting up. Inspected all fuses visually but didn't notice anything out of the ordinary. Any...
