The passenger air bag indicator light got pushed in so I need to get the vent panel off so I can push the light back flush. I do know the surrounding of the radio pops off without any tools. But taking that off doesn't get me anywhere. I still don't see access to remove the vents.
View 2 RepliesI have a 2006 Pontiac Montana, The little engine picture came up on my dash. I took it to the car parts store to have the code read and it came up as an O2 pre-heater sensor. My husband has been trying to google how to fix it and can't come up with anything. It doesn't even come up as to where the part is located.
View 3 RepliesI have a 2006 Pontiac Montana SV6 with 80,000 miles on it. Recently the dashboard warning "check gas cap" has started coming on. I have replaced the gas cap and cleared the code and it is doing it again. It seems like it is more likely to do it when the gas tank is 1/2 or less full but it also did it today with almost a full tank. The code from the computer said P0455, what this could be?
View 7 RepliesWe have a 2006 Pontiac Montana SV6 with the passenger sliding door powered. About 1/3 the time when we close the power door, it gets almost all the way closed and then it starts dinging and opens back up. Gets annoying when we just want to leave somewhere and we mess around with the door for 2 minutes trying to get it to close. We bought the car from a GM dealer and we have a warranty on it but they can't figure it out.
In my opinion, if they can't fix the door, they should replace it with a new one. If that doesn't fix it, then they should cut off that side of the car and put a new side on it. One of the two has to be bad. But I doubt that's going to fly with the dealer. They keep telling us they're "adjusting" the door to fix it but their "adjustments" never fix it. Where are the adjustments?
There's also sometimes I swear the door doesn't unlock so when we try to get it to open, it won't. Not sure if this is my imagination or if it's really not unlocking. Also the door rattles. You'd think the rattle would be related. The dealer says the rattle and the door not closing are two separate issue... but the rattle could be because the door is loose and the looseness is causing it to not follow the tracks right and then binds... I don't know.
Vibrates above 45 mph. Did have tires balanced . Still happens.

View 6 RepliesI have a 2001 Pontiac Montana that was overheating. It was low on coolant, and using coolant. I took it to a mechanic who checked it out and found exhaust gases in the coolant. He initially told me that it was a bad head gasket. After doing a bit of research, I am told that it could also be an intake manifold gasket. I know I am losing coolant, but I cannot tell where. I don't think it is going into the oil, as my oil level does not go up. I do not see coolant leaking below the vehicle, so perhaps it is going into the exhaust? Or leaking slowly on top of the engine where it is burned off before it can go on the ground.
Is there any test I can do to determine which gasket is bad before tearing into the vehicle? I thought about sending an oil sample off to determine if I am getting any coolant in the oil, but I don't know if that would be useful information at this point.
I have a 1999 Pontiac Montana that has recently started whining when I accelerate. It stops after I take my foot off the gas pedal. It usually takes about 15 minutes of driving before the whining starts. It started about 4 months ago and has recently become louder.
Van has 85K miles.
My van will rev really high when started and may stay that way for most of the day. Sometimes once it is turned off it will restart just fine. but when it is revving like this you have to hold the break down at stop lights, constantly slow down because it wants to take off. Now it is stalling when driving slowly. the throttle positioning censor has been replace a couple of times.
View 4 RepliesI have a 2001 Pontiac Montana van, when i drive i feel like there is just not enough power there. Most of the time when i hit 30mph the engine drops in power, hard to explain so I will try my best. I get in turn the key starts right up with out any hesitation what's so ever! I leave for work, while driving when I come to a stop sign and stop and take off its gets sluggish so while my speedometer is going up my movement is not changing as it should so needless to say I have to do 80 85 mph just to keep up with the average moving can at 70mph.
Once in a while I will give it some gas and let go of it and it would back fire a little not sure why. Recently I had new head gaskets put on cause temperature was not staying where it was suppose to be, they smooth out the headers and did a tune up, not sure about the timing, New fluids, once in awhile the temp would climb but that cause of the fans. Took it to AutoZone they did a obd code check came back with O2 senser and nothing else, so if I replace this will it bring my van back to normal running operation? And would it be anything I could check to rule out?
I have a 2004 Pontiac Montana minivan. I get a hard downshift from 2nd to 1st only when the engine is cold - especially noticeable in cold weather. After a mile or so of driving (or a few minutes of idling) is shifts fine. All upshifts are fine all the time. The tranny fluid level is fine and is in good condition. What it could be?
View 9 RepliesI have a 2002 pontiac montana that needs the head gasket replace. Mileage is 152,000 miles with a v6 engine. I would like to get at least another 75,000 miles once the repair is done. Is it worth doing as alternative is to scrap the van and buy a new vehicle...
View 3 RepliesWhat is causing the engine to sound like it's not getting enough gas AFTER we turn off the A/C? The two times we have used the A/C, after we push the button to turn it off, the engine sputters like it is going to die ... sounds like it is not getting enough gas. It has over 178,000 miles on it and it sat for about three years before it was given to us.

View 19 RepliesI own a 2002 Pontiac Montana van with 36,000 original miles. The past year it started making a loud whining noise that seems to come from the rear of the vehicle. It seems to be worse in summer than in winter. It iis really loud when turning into a parking lot or when turning sharply to go thru a drive thru at a restaurant. I have taken it to several mechanics and also to a dealership, and no one seems to be able to find the problem.
View 4 RepliesI flushed out my cooling system through the radiator with distilled water four times. It's a 3 gallon system, but I could only drain/fill a bit more than a gallon each time.
I figured that by the end of it, it's mostly distilled water so I only added antifreeze concentrate at the end. How long should I let the system circulate before I considered it well mixed and ready to test the concentration?
While driving my recently purchased minivan (a 1999 Pontiac Montana) for about 40 miles, I noticed the temperature gauge was reading high when I wasn't moving very fast, though short of what appears to be the overheating zone. Opening up the radiator revealed no coolant that I could see, but plenty of brown sludge. Looking under the oil cap revealed more brown pudding-type stuff (that wasn't there when I did an oil change when I first got it).
The lack of coolant makes me nervous that the engine might have overheating without the temperature gauge reading it properly. Is that possible? The heater was working, which searches seem to suggest means there must have been some in there.
I figure that either the intake or head gasket must be bad, so I'm nervously setting out to replace both using a gasket set like this: [URL] .....
What I'm more worried about though, is clearing the cooling system out of all the gunk. It sounds like oxalic acid and washing soda and back flushing might work? But I'm anticipating a large quantity of sludge, oily, rusty coolant water. How am I going to dispose of it all?
I have a Pontiac Montana minivan SV6 that is making strange clunking noises from possibly the rear or middle of the van when I go over a bump, large or small. I have had it in to our local mechanic and the local tire/repair shop and transmission shop. They have not been able to locate a problem other than agreeing that there is a noise.
Our mechanic replaced the front struts and strut mounts, the rear shocks and has gone over the entire suspension and transmission more than once. The noise is very loud, like something is broken but despite three separate shops checking it out nothing can be found.
Any possibility is could be something with the automatic side doors, such as the motor being loose or something strange like that? If it didn't have this clunking sound the ride would be very smooth and quiet. It doesn't affect the ride at all. The other bit of info here is that we haven't owned this van for very long, we bought it as is thinking that it needed shocks or struts. They've been replaced but the sound is still around!
I had a code for the EGR valve stuck open. I tried cleaning it but it didn't work (and didn't seem that dirty). Then I tried replacing it. Both times the code came back. What should I do now? I reset the code each time by disconnecting the battery.
View 14 RepliesI have a 2004 Pontiac Montana, and it just started making a low buzzing vibration noise when it's in motion. tone/pitch only changes with vehicle speed, not engine RPM. It becomes noticeable at about 20 MPH. Pitch starts low, gets a bit higher and faster as speed increases. Have looked for anything loose, nothing found. Braking is not a factor in the sound. Tires are good, Engine doesn't seem to be tied to the noise. Nothing noticed on body panels, air dam, etc... I suspect either transmission or possibly U-Joints.
View 3 RepliesI have a 2004 Pontiac Montana with 90K. If the overnight temperature has been below 40ish, there is a noticeable hesitation or stumble (almost as if the engine cuts out for a second-but never actually stalls out) on the 2 to 1 downshift when braking to a stop while the vehicle is in open loop. As the engine warms up the stumble becomes less noticeable until the temp gauge reaches the 1/4 mark at which point the stumble is gone. It won't return until the following morning - the next cold start. Our mechanic has cleaned the Throttle Body and the MAF- no change. Their transmission guy said he did not think it was a tranny issue. It has no other symptoms and seems to shift normally at all other times. What to do next??
