1998 Transport Power window by lolak70

My passenger side power window worked fine today, and then an hour later it wouldn't work with the passenger or driver side switch. Then when we got out of the van, my husband got a bad shock when he touched the passenger door. Any ideas what would be causing this?

It may be a an electrical short...could be as simple as a loose wire.

1998 Transport transmission/axle noise by fryman
Jun 13, 2009 (12:52 pm)

I have a 1998 transport that has recently developed a noise from the drive train (transmission, axle or wheel) that sounds like a prop plane. It increases in frequency and volume as speed increases. It is not engine, can shift into nuetral and the noise will continue, winding down as the car slows.
When I lifted the front end and took off the wheels to see if I could pin point, the traction control turns on and applies brakes (without track on the wheels) so any idea of what the problem is would be helpful.
I need this car to last another two-three months so if this is something I can drive on, so much the better.
Thanks

overheated 1997 pontiac montana trans sport by nthompson1

I recently bought the above van, and immediately discovered a overheating problem which occurs in driveway while idling, and also driving a mile starting cold. Before I bought it, I sat in the passenger seat while the previous owner drove it a short distance, so I couldn't see the gauges. Of course, the owner claims it never happened before.
First, gauge on the dash goes all the way over to hot, then the lighted water signal says hot, then the check engine light goes on. Then the engine dies but restarts easy.
When I first looked at the engine coolant reservoir at the owner's house, it was almost full. Now it is full to the top, and the radiator is short 1/2 gallon.
The previous put 1/2 gallon water in the radiator at my house.
When we started the engine again, the radiator fluid is sucked out somewhere, again 1/2 gallon short.
My thought is to take another car to the store and buy the DEX-COOL recommended in the manual, drive the trans sport to a parts store to get tested.
My "new" trans sport has 186,000 miles. It has 13 car faxes(cost $40 to get).
Is it possible there is a simple solution?
I am VERY wary as I just had a master brake cylinder installed on a 1991 Dodge Ram Pickup. It doesnt brake any better, and now am told it needs at least new brake lines.
I am a deserving person who needs your help. Thank you.

Sounds like a wheel bearing assembly to me. Easy to change but the part is fairly expensive. If one side is gone then surely the other side is close to going. Good luck.

Check your engine oil. I bet it is over full. If so you have a blown manifold gasket. Sounds like the correct mileage for this engine. The dexcool eats away at the cheap OM gasket. Have it changed to the metal reinforced gasket and you will be good to go.

If you have all wheel drive, no, a full size wheel will not fit in the spare stowage underneath.

Thanks so much for the quick response. I am saving and printing all Internet postings re this problem before I take it to a repairman.
Message #1229 and #1230 also refer to a faulty intake manifold gasket.
See www.oldsmobileforums.com/forums/showthread.php?t=8233 posting by 442much. This gives details of class action lawsuit against GM in Canada after CTV Whistleblower report that reveals in detail this same problem in millions of GM vehicles.
My mechanic in Iuka MS told me to check the underneath of oil cap; if it has yellow gel, that means the intake may have a leak. I checked this before I bought the Trans Sport; and, it does not have that.
I am in SW MI.
The engine oil is not overfull; but 1/2 gallon extra may not be enough to change the visible level on the stick,
The actual mileage is 180,145. It would seem that someone would have had to have changed the OM gasket before now. Maybe it went bad again.
The plastic engine coolant reservoir does not have a full hot marker, only a full cold. There are 2 small holes drilled in the top; one has a black plug in it. The other hole is open.
I deeply appreciate all replies. If this ends up to be an inexpensive repair(under $100), I will be a happy camper.

Pontiac Montana 2001 Overheating!!!!! by shanesmom

My 2001 Pontiac Montana overheats when slowing down or is at an idle. We have changed the water pump, thermostat, radiator, intake manifold gasket and it still over heats. And bleed it until I was bleeding. Any suggestions?
