#49 of 102 Re: AC only cold on one side; temp gauge is wrong [heather_ebay06] by mililanisoccer May 31, 2008 (5:06 pm)
Replying to: heather_ebay06 (Jun 15, 2006 5:38 pm) I'm having the same problem with the AC. Driver side is blowing hot air while the passenger side is cold. Both the Driver and Pass dials are set to 60 degrees. It almost seems like a vent valve is stuck.   Any recommendations?   thanks, jeff Replies to this message: 01intrigue (May 31, 2008 7:13 pm) rosscm (Jun 19, 2008 7:00 pm)

If it's getting power to the clutch and compressor isn't spinning, the clutch is bad. Next quick check is to see if the servo motors are working on the mixing duct. Pull the A/C fuse and turn on the key but don't start it. Plug in the fuse and listen closely under the dash near the center. Should hear the servos sweep the damper from open to close to calibrate the circuit. If you don't hear it, problem is likely the servo. I had to change the driver's side on mine as it was blowing hot when the pass side was cold. If the compressor is running and still no cold air, check the pressure. My compressor lost a valve and it just quit pumping. No noise and immediate failure. Had to change the compressor. Refer to earlier discussion in this string. Good Luck!

Replying to: mililanisoccer (May 31, 2008 5:06 pm) This happened once to me (cold on one side, got on other.) After re-starting the car, the problem went away. Dealer said that a switch can get stuck. Have you changed settings to force heat instead of AC? In other words, make the switch do something outside of how it is set now. You might try disconnecting the negative cable on the battery to reset it. (This is how to get rid of a ServEngSoon light-on as well.) If it does not reset to normal, you need to replace a part. Sorry, that's all i can supply on this one. (Our family has two 'trigues and my brother's family also have two. We like these cars. We are tall and the have the most front-seat leg room of any car I would want to drive.

Replying to: mililanisoccer (May 31, 2008 5:06 pm) There are fuses on the right end of the dash board. You have to open the passenger door to see the panel. There is a finger hole for yanking the cover off. A "Fuse Usage Chart" is on the inside of the cover along with a few spare fuses in a foam cushion. The first row down and "B" across says "LOW BLOWER 20 A." I noticed on the panel that the corresponding slot was empty so I pulled a spare 20A fuse out of the foam cushion and placed it. It did seem to me that my problem went away. I was having forceful air in the drivers side but no heat, and the opposite - heat but no force - on the passenger side. It is summer so the air is going to seem hot no matter what but I did think the air was blowing hard on the passenger side now.

Replying to: oldsgeorge (May 31, 2008 6:06 pm) Oldsgeorge -- Would you happen to know the part number for the driver's side servo that you replaced? All I'm able to get from the dealer is the entire control module.   Thanks! Replies to this message: bluevolume (Jun 23, 2008 5:35 pm) rtownsend2008 (Aug 02, 2008 2:54 pm)
#54 of 102 A/C Damper Servo Drive by oldsgeorge Jun 23, 2008 (5:26 pm)
It was an aftermarket part and I don't recall who I got it from. Thought it came from RockAuto but I checked their site and didn't see it. It has the letters CEI and YPP-6F30 stamped on the case. Bar code number was 52402588. Hope that helps.

Replying to: bluevolume (Jun 23, 2008 12:36 pm) OK, so I found the part number myself when I took it off (its 16163982 for anyone who needs it). I removed the actuator, and I still cannot figure out what is wrong. I can move the blend door from end to end by hand, and it feels and sounds like it is sealing on either side. Even when closing it by hand, I'm still seeing a good 15 degree temperature difference between the driver and passenger (when set to coldest temp).   Is it possible that the blend door is cracked or something? It doesn't feel like it is binding or loose or anything. Could it be a faulty bypass for the heater core? I'm assuming that it has a coolant shut-off for the heater core when on A/C. Maybe that is failing, and it is heating up the drivers side more?   Any ideas, before I tear the whole dash out?   Thanks! Replies to this message: rtownsend2008 (Aug 02, 2008 2:54 pm)
#56 of 102 A/C Damper Servo Drive by oldsgeorge Jun 24, 2008 (4:02 pm)
There's no heater shutoff valve. Hot water is available to moderate the temperature when the A/C is on. Sounds like the door is still attached to the shaft. I doubt a crack would let enough air by to cause the temp difference you see. Could be something preventing it from closing all the way but anything is just a guess. Would be interesting to thread a boroscope down the vent and see what is in there. Good luck finding one though. Not many shops have such an expensive tool. Let us know what you find.   Regards Replies to this message: bluevolume (Jun 24, 2008 6:27 pm)

Replying to: oldsgeorge (Jun 24, 2008 4:02 pm) My neighbor works at a Pontiac dealership, and he after doing a little research he came back with "low on refrigerant". I didn't think much of it, since I already charged the system yesterday, so I went back to troubleshooting.   Just for grins, I decided to check the pressure on the AC system again, and I found that it was still on the low side (~22). This is where I realized that with the connector i have, you have to press it down and hold it for it to open the valve. When I was filling it yesterday, all I was filling was the hose and the gauge.   After a good charge, I think I'm back in business. The air is still a little bit cooler on the passenger side, but overall it is fine. So, for everyone who has had this crazy problem, being low on freon can be a big factor.

Replying to: bluevolume (Jun 23, 2008 5:35 pm) I too am having the same problem with my 2000 Intrigue.   Could you give me a general idea as to where the actuator is that you were able to remove prior to tearing out the entire dash? I'm looking around and I can't find anything to check.   Much appreciation.   Russ
