I also own a 2001 Montana and have had ongoing problems with the van. In 2003 we replaced the condenser and the compressor $2000.00. This past Friday July 28,06 we brought it in again to the dealer for what was diagnosed as a cracked condensor, again! Cost to fix $1100.00. We didn't have it done. It was not a pretty seen at the dealership. They told us we needed to talk to GM about the problem. I did contact GM back in 2003 and got know where with the problem.
I will call again on Monday.
I am amazed how many people have had problems with this model.
We also had to have new brakes, Head Gasket, Wiper motor and ongoing items I can't reemember off the top of my head. The worst part of the whole thing is I still am making payments on the loan I took out for this van!

Hey, we have a wiper motor problem too! Does someone program these things with specific life spans or something?! Just ordered one from NAPA and picking up on way home. Also just got new brakes a month ago. Ours is an 04 model though. I guess with the new models they're getting worse and not better...

I fixed a wiper motor problem by running a separate ground wire from the motor to a screw on the frame. It seems these motors are not grounded very well. No problems for 80,000 miles since the fix.

#7 of 94 A/C problems, replaced compressor & condensor by ncjack

Aug 02, 2006 (6:40 pm)

I have 2002 Pontiac Montana with approx.76K. Just replaced compressor & condensor. Mechanic says everything checks out ok like Freon, etc. The left (2) of the (5) vents in dash are blowing very warm, humid air while the remaining (3) vents in center & right feel cool not cold but dry. Any clues to this problem?? I just spent $1400 & we're still very hot with no A/C. Any help will be greatly appreciated!!

#8 of 94 AC problems in 2000 Pontiac Montana! Help! by tanjo

Aug 04, 2006 (6:40 pm)

I am having a problem with the AC in my 2000 Pontiac Montana Van. Even with the air conditioning on high, it blows hot air. I had it in to the mechanic and he couldn't find a problem, but suggested we put dye in it to see if they could find a leak. They couldn't. He had recharge it and it worked for a couple of days. A few days later, it was blowing hot air again. After looking at it, he suggested that we bring it to a dealer to have them look at it (as he couldn't see anything), and let him know what they said. We paid for an hour tabour at the dealer for them to tell us that we needed a new condenser and that they were not sure if that would fix the problem or not, and they again suggested the dye. We brought it back to our mechanic with the news, and he said that he had checked the condenser, but didn't see a problem. We decided to have our mechanic put in a condenser, it cost less than half than the dealership quoted. Well, here we are a few days later, and we are getting hot air again...
  
What should our next step be?
  
Thanks in advance for your help!

Found out mine was the control on the dash - when I put it to cold, it would blow warm - would never go all the way to cold. There was nothing wrong with the A/C, just the mixer. Get a manual and dig into the dash to loosen up the linkage or check the vacuum that runs it.

#11 of 94 03 Pontiac Montana Heater problem by mlhile

Dec 12, 2006 (7:57 am)

Our 2003 Pontiac Montana will only blow warm air from the heater when the vehicle is moving. Vehicle blows only cold air when stopped. The higher the speed, the warmer the air temp. Can feel the temp cool as you slow and stop. Recently took to mechanic who couldn't find a problem but cleaned heater core which did allow for warmer temp while driving. Have a newborn and live in a cold climate so it's very important that we are able to warm up the van and maintain a warm temp when stuck in traffic. Any ideas?

Hi the mechanic obviasly check the coolant level, that being ok. I would replace the thermostat. If your in a cold climate you can also block part the the rad, BUT YOU MUST HAVE A GAUGE TO KEEP AN EYE ON ENGINE TEMPERATURE!
 
 PS anyone have any info on my transmission
