AC problems in 2000 Pontiac Montana! Help! by tanjo

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.

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

I just bought a 2002 montana and notice that my engine temp. rises more than half the gauge but not reaching the red portion. I went back to the dealer and he told me that it is normal for montana's to have this temp. I just want to know from you guys if it is really normal to have this engine temp.or theres somthing wrong with my engine or gauge.
 
thanks and hoping for reply

i went to GM dealer to have my key duplicated and programed and i asked one of mechanics if it is normal to have this temp. fortunately he also owned a 2003 montana and he told me it is really normal coz he is also having this kind of temp.

We have a 2000 Montana and have the same thing with the temp gauge. It usually is caused by a slow leaking lower intake manifold. Common in GM 3.1 and 3.4 V6's Just keep a check on the coolant level.
