Some info for those experiencing this problem: (Limited with Auto A/C controls) Check the vacuum tank connector and tubing behind the front bumper area on the passenger side. While working on my Mom's car trying to fix this problem, I removed the connector from the vacuum tank and it snapped off the tubing instantly. The tubing had become brittle and I believe was leaking vacuum, causing the actuators to not move in their full motion. I reamed out the old tubing stuck in the connector with successively larger drill bits (cordless drill on low speed), then inserted the existing tubing back into the connector. I pushed it back onto the vacuum tank fitting, started the car and the dash vents (MID setting) were again blowing air. The vacuum tank is clearly visible in front of the passenger tire and behind the bumper. It's about a 4" diameter black tank with black tubing connected to the front of it. I stuck my head under the car about a foot without the need to jack it up. Be careful pulling off the connector to inspect it. The vacuum tank appears to be made of pvc and the fitting on it may be brittle also. I did this after pulling the programmer from behind the glove box and testing the solenoids and tubing. All appeared to be functioning normally. I then observed the vacuum actuators behind the dash (looking up from underneath the dash) as my wife pushed various buttons on the A/C control unit. The actuator arms moved, but only maybe 1/4" or so. After the vacuum connector was fixed, the actuator arms moved a good 1"-2". Short actuator arm movement would be a good indication of a vacuum leak. Hope this info helps somebody. It took all of 2 minutes to check the connector and 5 minutes to fix it after it snapped off. A lot easier than taking off the glove box and programmer unit! Good Luck - RangerDave19 |

I recently purchased a 1995 Buick Lesabre Limited with 150k miles on it and an automatic climate control unit. The air will not blow at all on any setting, but the control unit in the car works. A friend said that there appears to be no electricity going to the blower motor(He used an electrical meter) when I changed the tempature settings in the car. He said it could be the climate control unit in the car or a fuse but I do not have the fuse panel cover so I do not know where the fuse is located. I would greatly appreciate any advice and advice about where to find a fuse panel cover or diagram.

Replying to: rayslesabre (May 13, 2009 7:42 pm) The check is to take the leads from the blower motor and apply direct battery power through a fuse--please use a fuse-- and see if the motor works. They do die. Then follow the leads from the blower motor up to the left to the top of the channel that the air goes through from the blower. On top of this boxy channel is the end of an electronic power transistor that controls the blower speed. The circuit board part sticks down into the air stream inside the box for cooling. You can access this by removing two screws that hold the Relay Center to the firewall above it. The wires to the Relay Center have enough give to move it up some and allows access to the screws holding the blower control module. You can buy modules at rockauto.com, gmpartsdirect.com, and other parts stores. You also can use recycled from wrecked cars. Just check the parts numbers. Or search on car-parts.com; you'll see the interchangeable ones from other cars.

I think I have the same problem with my blower motor. The air coming from my AC is cool, and the defrost works when I am driving because enough air comes through the vents, but the blower started working intermittently some months ago. Sometimes it would come on after I had driven a while, and then I noticed I could hit a bump and the blower would come on, sometimes. Then I found that closing the passenger door would start the blower, and this worked for a while. Yesterday, I noticed that the fan would start weakly and then gradually build in strenght, but then it began weakening and then quit. Bumps and slamming doors do not seem to be able to revive it now. I have priced blowers, but someone said it may not be the blower. It might be a loose wire or a sensor. I don't want to buy something I don't need. What do you think? Do I need a blower, a sensor, or simply some wires reattached?

Replying to: elainee (May 23, 2009 10:47 am) You can test it by using a FUSED wire from the battery along with the ground wire and disconnecting the power to the blower and substituting the power leads from your battery. If it runs fine then, your problem is the blower motor control module or resistor pack or a connection. Most likely it's the blower motor has worn out. There are 5 screws holding it, more or less, and it comes out toward the motor and can be wiggled out. Some people push the car forward in park and block the rear wheels which twists the motor slightly forward leaving a little more room. Replacement motors for those years are relatively cheap at various stores or rockauto.com.
