Question about 2002 Pontiac Montana

1 Answer

Air shocks stay fully pressurized an won't adjust for normal ride

I had new tires put on my 2002 Pontiac Montana and now the air shocks stay fully pressurized. Raising the rear end to the maximium. If I unhook an air line at the shock the pressure drains off and after I hook it back up, in not much time they are fully pressurized again. Is there a way to reset this system so that it works properly. The tire company was baffeled by this. I think that the air system should have been turned off when the car was raised.

When the air hose is disconneced from the shocks the air goes out and the rearend drops to its normal position . why does the compressor run weather the air hose is connected or not


There is a pressure switch in the engine compartment that needs to open when the pressure is correct. Follow your air line to it. Sorry, i need to see it to say any more.

How to reset the computer on a 2002 pontiac montana


Which computer are you wanting to reset? There are at least 5 on your vehicle. The next question is WHY do you want to reset it? Are you trying to clear fault codes or are you wanting to clear adaptive learning stategies? or BOTH? Are you having a problem with warning lights coming on? If so, have the problems been corrected that CAUSED the lights to come on?

Anyway, a scan tool is required to reset ANY of the computers on your vehicle.

Had shocks replaced at a ntb service center all four of them, also four new tires now the ride is not smooth as before,plese help


Tire centers tend to over inflate tires. You probably have become accustomed to a softer ride. Try lowering tire pressures a couple of PSI but be careful, to low a pressure will affect handling. The factory tire pressures are in your drivers door sticker.

TPM light stays on. All 4 tires have 26 lbs of air. What is recommended tire pressure?


32 psi is the usual recommended pressure but you may have to fill the tires to 35 psi to make the TPM system reset. That's how most systems recognize that you have serviced the tires. Most TPM systems will indicate low tire pressure around 26-28 psi.

I need a picture of the rear air shock compresser shown with the air lines hooked up to it. i put new shocks on ,but they still do not work. an air line was off. but i am not sure where it geta connected.


i think its in the back under a plastic side compartment -its no big deal its just a little 12v air pump for the shocks in back if you wanted to u coul by pass it and get some plastic fittings from pep boys and put air in manualy like u would a tire - i have a 98 transport it has been a real pain with tailghts burning out front turn signals burning out and one day the wife brought it in all jacked up and the pump wouldnt shut off it was a cheap plastic arm under the van broke off the axle nothing but a simple on off swtch i duck taped to the axle -fixed 1 month later the motor blew up started to get hot head gasket or somthing - now im trying to get a 2003 just regular montana on the road everything works runs good but cant get the odometer to stay on im thinking about just lookin around for some "hot" inspection stickers when this goes ill never own another gm van -i think ill go japanese or somthin these things are just plain cheap junk
