Replying to: m20c (Apr 03, 2009 1:38 pm) http://i86.photobucket.com/albums/k110/imidazol97/IMG_2157.jpg At the middle left of the picture is a white arm with a thin threaded rod that goes to the right about 5 inches to a little white plastic arm that is part of an actuator. By taking off the hush panel under the dash (3 screws and two taps at the firewall) and maybe taking off the glovebox door, you can see that arm. By moving it while the key and heater are on, you should see it go right and left to change the blend door to give the temp you want. It may be unsnapped from the arm. It just snaps on sideways and you would have the door at the left inside the heater on full heat and the digital temp control at full heat request (90) and then snap on then. This picture may help more. These have had the dash removed for some kind of work. Yours can still be reached but will not be this easy, depending on the year. http://i86.photobucket.com/albums/k110/imidazol97/HeaterCore1-1.jpg The actuator may be burned out or the gears cracked. They are available at rockauto.com or gmpartsdirect.com. You'll need to be very careful you get the right one for your car. IF it is bad, you can take the actuator off with two screws-not easy to get at one, and check the part number on it. Put that part number into the blank on gmpartsdirect or rockauto and it will give you the right replacement.

I have a 2000 Bonnie SE, the passenger side blows super cold air without any problem. However the driver dash side only blows hot, with just a barely noticeable smidgeon of cool if at all. It's a dual zone electronic with digital readout, the rear passenger outlet is also warm. Air flow seems to switch areas selected without any problem. about 3 months ago, autozone guy, put in some freon in one of the 2 lines that run parallel to each other alongside the fender wall, it seemed to help. just a tiny bit, nothing to be elated about. Asking the passenger side outlet to cool the whole interior, just won't do it, and pointing the outlets toward the driver for some relief, won't do it either. Bottom line--Drivers side does not cool- (Nor do the middle ones on dash). PLEASE HELP, can't afford a mechanic and need to drive to LA to visit with my son who is on his 4th tour to Iraq with the Marine Corps, the interior gets very hot for my wife and we must drive during the day from Arizona . I anyone can tell me how to tackle this problem, we'll be forever grateful. If some one can tell me where to look and how to get to it. I have no problem tackling it. THANKS IN ADVANCE FOR YOUR HELP. |

Replying to: bonnarizona (May 18, 2009 10:24 am) If you have some expertise, you can get a 134a can with a gauge at Walmart or other store. Do not get the ones with sealer, dye, superfreon, in them. I bought a separate gauge they had and just buy the plain cans. Recharge with the motor running and the heater fan blowing on high to the pressure they indicate on the gauge. You'll probably find your cooling is back. If there's an actuator problem inside the car that moves the vanes that control the air, that too can be changed by a fairly knowledgeable home tech type. If when mornings are cold and you have the heater on, both sides can heat and adjust with heating occuring, you probably just have low refrigerant. If the actuator is slipping, you may have trouble with heating settings. |
