#1476 of 1485 Temp control stopped working
Oct 19, 2011 (8:56 am)
The red/blue temp setting knob isn't working, we get full hot air. The knob turns very easily, I suppose there's a physical connection that's slipped/ broken/ worn out. Does anyone know if there's something in there I can fix myself?

Weird. I just got home, my wife reports it's working now. Still, I'd be happy receive comments.

Had a look at replacement units on ebay, looks like the control connects to a wire harness, which I guess may be loose in my car.

All speeds except 1 and 2 worked on mine. Its a bitch to get out but pull the motor and pull the control board, if burnt like mine just repalce it (wreaking yard or new) and you'll be good to go. Mine was obviously burnt and low speeds did not work at all. Maybe your's is on the way out but still "kinda" working.... good luck. Kennie

If you have two original keys, which you should have, plus the new pk3.
Go to hardware store or locksmith and have it cut.
1. Insert the first original key into ignition, turn to on, but don't start engine.
2. Leave on for about 5 seconds.
4. Insert second original key. Turn to on, but don't start engine.
5. Leave on for about 5 seconds.
7. Insert new pk3 key into ignition, turn to on, but don't start engine.
Leave on for about 15 seconds. Start engine.
I am not sure but if you have three keys you may have to insert it into repeat steps 1 -3 before if you have to step 7.
I have successfully programmed my pk3 in my 2002 Pontiac Montana, using steps 1 through 7.

I am having the same problem and it is driving me nuts! I have replaced almost everything and can not solve the problem. When you first start it up it cranks over smooth first turn. Then at random intervals while driving it will just turn itself off and the power steering goes away. It scared the hell out of my kid and we really did almost get creamed by a big truck. Thank God for that trucker's skills and reflexes because he barely missed us, pulled over, and came back to help us and call for help. The crazy part was when he said that another buddy of his had a similar problem with another Pontiac Montana and suggested that I wait 20 minutes and try to start it. So we did and it fired right up like nothing had ever happened. It has done this at least a dozen times since and as I said nothing I do to it seems to help in any way. So, Please, I am open to any suggestions. Help!!!

I had this problem last August, 130650 miles. The dealer service dept replaced the ignition switch and it's been just fine ever since, but the diagnosis involved the technician referring to a "TAC case" to figure out the problem.

If you email me at chrisleb1aol.com I can send you a scan of my repair sheet- it has some diagnosis on it.

I had a 1998 Pontiac Trans sport but salvaged it in Oct 2012. over 100,000 miles on it and found oil in the radiator this time. It was her time. Wow I had never had stalling issues with the van though. That can be scarey!! Have you checked fuel filter and the fuel pump? Almost sounds as if your not getting enough fuel pumped up to the engine. Could be that or the fuel injectors are in need of cleaning or replacement and or the fuel pump/filter.
