Pontiac Montana QuestionsRefine by vehicle
My inside lights do not come on when I open my door
when you get up to around 50 mph the transmission will make a loud bang and then the van will jerk this only happens once in a while
when you stop and start right back up the right rear brake will lock up for a few feet before letting go
this started after it overheated while my wife was driving
i turned the key an got nuttin but all the lights radio etc worked. i turned it off an back on an got nuttin i waited a few mins an tried again an only the seatbelt light came on everything else is dead including the power windows last time it did this my radio an time reset back to default
How do I fix the security so the van will start
My driver side front door recently stopped latching correctly, and water leaked started to leak in from behind the temp/MPG readout on the ceiling.
I can also hear the wind whistling outside from both the driver side front, and the passenger slider.
The van has 150k miles on it, and so far has run like a charm, but in Michigan, Rust kills... is my frame starting to buckle?
I went to the gas station and when I came out I put the key in the ignition, it dinged once then nothing. I got a jump an hour later. Let it run for about 15 min. Turned it off and immediately wouldn't start I don't know how to get to the battery with the fuse box on top to check connections.
I know it was a recall but because of the mileage I can't get GMC to replace it. I want to get a used tank from a newer Montana but don't know which years would be the same tank but without the defect.
What cause van to not start. Acts like has no battery. When turn key does nothing.
is there SENSORS IN THE BUMPER
I have a 2000 Pontiac montanna and its winter and I think my fuel pump went out I don't want to drop the gas tank, is there a way to get to it from inside the van..under the seats?
Not getting the fuel, I replaced the inline filter, but still nothing.
Heat also works in the front of the van but not the back.
CLEANING THE RIGHT REAR WHEEL SENSOR (CHANGED AXLE DUE TO TORN BOOT) DIDN'T HELP. NO BAD SOUNDS. PROBLEM STARTED AFTER PUNCTURE IN REAR TIRE WAS REPAIRED - WHEEL REMOVED AND REPLACED BY TECH. THAT SHOP SAYS "THEY DID NOTHING". COULD THE WHEEL SENSOR HAVE BEEN DAMAGED BY THE TIRE GUYS?
The power operated door will not shut. You can push on it and it look like it shut but as soon as you let the pressure off of it it comes back. It is almost like it won't clasp.
The rear doors don't open and close the way they should all the time. And the buzzer stays on saying a door is open when they are closed.
While driving my RPM went up and my van stuttered a little. It mostly happened after a complete stop and then pushing on the gas. It also happened while pulling in to parking lot. What causes this?
It has many miles and the motor is getting tired. Under power and in gear it started to fall on its nose, loose speed. In park or neutral you can throttle up and all. But under power and in gear you can not get over 2000 rpm and around 25-35 mph. Up hill maybe 10 mph. Thought maybe catalytic converter was plugged and drilled 3 holes in the side of the converter. It is doing better but only 10-20 %. The time from fine to only short runs ( less than 20 blocks or so ) was about 3 months. There was a slipping of the transmission prior to current state.
. Someone said it may be the coil packs too. I need better input I van not afford to take shots in the dark.
The other day, while driving, my van went into serious overheat mode. We had just checked the fluids and they were fine. I checked the antifreeze reservoir, it was completely empty so I filled with what I had left in the jug. The heat gauge went down and all seemed to be ok. The reservoir needed filling a couple of times, but I thought that if it had actually leaked out, that would be normal. 2 days after, when I started driving, the motor started squealing like mad, van could barely be accelerated, seemed like very little power. We decided it was the water pump and changed that. That reduced the squealing but didn't stop it. The van did run better. However, during the trip, I ended up with no interior heat at all and the van did start to overheat slightly. I thought that maybe we hadn't filled the rad enough and planned to fill when I got back home. After driving for about 45 minutes, I started to get some heat but then seen vapour pouring out of the engine compartment and really overheating again. A lot of engine knocking/rattling also - before and after water pump change. Checked the oil, it wasn't really milky but there was a tiny, tiny bit of white residue on the dip stick. The dipstick indicated overflowing oil... wayyy up on the dipstick but the crankcase seems empty. Are these all related issues or do I have a ton of problems on my hands? Thanks in advance for any and all help.
Drove in morning 4 miles temp clear to red. Garage flushed pressure tested; ok. 2 days later same thing; replaced fan switch /relay; ok. Drove over 50 miles. Next morning 4 miles same thing; replaced thermostat and bled each time; ok; sat overnight and same thing again. Any other ideas.
