#3761 of 3823 replacing rear brake cylinders
Sep 26, 2006 (4:10 pm)
I have a 2002 Malibu. The rear brake cylinders are beginning to leak. I need to replace them. Chevrolet rear brakes used to have hold down springs. However, recent GM vehicles have a curved steel bar that acts as a hold-down. The last time I took one of these off, I had a devil of a time trying to reinstall it. If you have any suggestions for this please respond.
Thanks, alfalfa 328

Seeing as the oil pressure switch is suspect why don't you go ahead and change that as well? Can't be too expensive. It's better than being stranded somewhere far from home.
#3763 of 3823 how dealers vary wrt the same repair request
Sep 30, 2006 (7:28 pm)
still trying to get the stupid tech bulletin fix for my front end done:
dealer 1: kept car for a day (I had to pay for transportation rental), claimed they could find nothing wrong. Return visit had dealer service rep claiming they would do the bulletin provided the parts had not been previously replaced. 2nd return visit with proof of earlier repairs showing part numbers were different brought denial from the writer who then said the service manager had to clear it and he was only there on weekdays.
When I asked the dealer to do the repair and I would pay for it, they said no dice, as their belief was I could then claim warranty against them after repair was done (huhhhh? If I __ask__ a dealer to do something and __authorize__ them to do it while paying them to do it, I see no way I could claim anything other than parts warranty for work they did).
dealer 2 also could find nothing wrong, but said they would do work if asked and paid. Bill was estimated for $400. I said I would wait and see how this repair actually held up.
dealer 3 is in progress now via a more helpful writer; will hopefully have results to tell by end of week.

Hi there, a year ago almost to the day I had a problem with the heating on my 04 Malibu. You told me to remove and replace fuse HVAC CTRL(BAT) on the passenger side fuse box. It worked for a while and then died and then on its own started working again the whole of last winter. I thought I had found the problem in a loose plug.
I have the same problem again. No heat. I notice that the heater core on this model always has hot water flowing through it. Heat seems to be controlled by the heater door only. There are no water valves.
The problem seems to be that the heater door remains in the closed position cutting off hot air to the cabin. When I remove fuses HVAC CTRL (BATT) and HVC CTRL(IGN) and then replace after 10sec and then switch on ignition, I can hear the door and feel the motor running (flapped down glove box and put hand on motor). The door runs to what I assume is the open position for hot air but then returns to the closed position. Does not matter where the temperature control knob is set.
In running to the open position for heat, the motor runs slower and slower before returning back to the closed position. When returning to the closed position there is a positive stop as if a limit switch has cut in. Thereafter there is no more action from the door unless I pull the fuses again. Turning the heat control knob has no effect.
My feeling is that the limit switch (if there is one) is not working in the open door position and is confusing the BCM. It's such a schlepp to take the car to the dealer. Do you perhaps know what I could do? Could you tell me if there are limit switches and, could I possibly get access to them without tearing everything to pieces? Sorry for the long post.
#3766 of 3823 Annoying Signal Light
Oct 02, 2006 (8:12 am)
I have a 2000 Malibu and the noise the comes on when I activate the signal light stays on even after the signal light has been turned off. I'm not sure what to do as the noise has lasted for up to 20 minutes continuously. If anyone has any suggestions it would be most appreciated. I'm not exactly sure how this happened but it is fairly annoying. My "Check Engine Light" came on today, but reading through these posts I now have a good idea on what I need to to about that. Thanks guys.

BCM doesn't have anything to do with this. The HVAC control head itself has the electronics which control the actuators. In this vehicle the controller uses a "pulse count" method for knowing the position of the actuator. I really don't know exactly how it works, sorry. I do know there are only 2 wires going to each actuator and so if the actuator is moving then the wires to it are both connected.
There isn't any limit switch.
By pulling the HVAC CTRL (BATT) fuse you force the system to lose its memory of motor position so when you reinstall fuse the system goes thru a relearn cycle.
There are 3 motors in system. There are 2 on right side of vehicle around glovebox for recirc door and mode control. The temperature door actuator is on left side by the pedals.
I don't have suggestions at this point. Sounds like dealer is going to have to look at it and I would suspect they end up replacing the temp door actutor or HVAC control head.

Thanks for that. The only motor that runs after fuse is pulled and replaced is the one by the glove box. If you squeeze the glove box and then let it hang down you can see it. I can feel it running by putting my hand on it. Yes, there are only 2 wires going to it. I don't hear any other motors running but will look again tomorrow. They must be using stepping motors for the actuators.
#3769 of 3823 Smell of Burn Oil after Oil Change
Oct 02, 2006 (7:19 pm)
I had my engine oil changed at jiffylube yesterday. After I drove home I smelt burn oil, and I also found a small amount of smoke after I opened hood. So what happened? Does anybody have such kind of experience. Thanks a lot.

Yep, just happened to me yesterday after I changed my own. As the filter is removed, the oil gushes out, splashing on to the exhaust pipe. There should be no problem, and the odor will go away in a day or two.
