#82 of 116 program mode not working by auto123 Jan 10, 2009 (11:52 am)
I just got my 2003 Pontiac Montana back from the transmission shop -- major work, not sure if it's 100% -- but that's another post. Since it was all pulled apart, a number of electrical things are not working: the automatic door lock, the power sliding doors and the parking aid are all non-functioning. The first time a tried reprogramming the locks I was successful at entering programming mode. The chimes indicated that the door locks were set at Mode 3; however they were not functioning that way and, when I tried to set at Mode 4, nothing happened. Now, I am unable to even enter programming mode. The manual indicates you're supposed to hear 2-4 chimes when you enter the programming mode; I'm getting 5 chimes. Any thoughts? Thanks, in advance.

Replying to: 05montana (Jan 19, 2008 6:25 am) I live in the Netherlands and my good friend with a recent Montana also is having major problems with first the temperature guage going bad and then the fuel and speedometer going bad. Please make a post to this site is the dash cluster fixes the problem and the approximate cost. I have read several posts of eltrical shortages in the taillights and will check that out immediately.   David
#84 of 116 1998 Trans Sport Montana by rstonehouse Jan 27, 2009 (4:41 pm)
Hi Folks. I just bought a 1998 Trans Sport Montana with 125K. The Engine "seems" to OK??? However I am concerned with the Dexcool problem with the Head Gaskets. After 125K, the gaskets may or may not have already been replaced. Is there a failsafe way to check to see if I may be facing a gasket failuer in the near future??? The problem I have already encountered is with the auto lock system. In short. it doesn't work!!!! LOL The auto sliding side doors do not funtion and the rear gate can not be opened even with the key!!! I oliterrally just bought the car today (01/27/09). I have numerous switches and have ppushed many off and on several time to see what they do. Perhaps I disabled the auto Door Locks??? The side doors seem to "Rattle" a lot on rough roads, and the rear end seems like it could use new shocks??? IN any case, I think I will be needing the expertise and experience of everyone on this site to help my diagnose and fix what seems to me a multitude of mechanical problems. My primary concern at this point is to determined the condition of my head and manifold gaskets!!! Any and all infowill be greartly appreciated!!!
#85 of 116 Turn steering wheel to left or right causes van to shut off by Cruz70 Feb 18, 2009 (7:39 am)
My husband recently purchased a used 1999 Pontiac Montana,The van runs great except for when purchased the pass key light and the ABS light is on, He was told all he had to do was replace a sensor to fix those two things but now it seems after putting the van in reverse trying to back up, when the steering wheel is turned to left or right the van shuts off? What could cause such a thing? I'm not mechanically inclined and my mechanic has never heard of this issue. Would these two issues be connected?R.Cruz

Replying to: santana12 (Feb 19, 2009 5:55 pm) Well, could be a number of things. I'm no expert but in the past, if you steering wheel is locked then your van won't start. It locks when the key is removed. If you put the key in, turn it just enough that the steering wheel is movable in both directions - you should be able to turn it, although hard, it will turn both ways. Then start the vehicle - sometimes when you turn the key the steering is pushed in one direection too far and the computer 'thinks' that someone is trying to steel the van. Another thing is that your battery terminals are dirty - be carefully about disconnecting battery if your radio is the kind that locks if the power is removed you may need to take your radio out and prove to a dealership that it needs resitting (pain in ass - this is not the case fro the 2000 montana). Another reason is that somone put a key in the ignition that is not coded to the vehicle and the computer shuts everything down - i'm told only for 10 to 15 minutes then your keys will work again. Well this is not the case for me... I had to reset my computer (either that or the steeing wheel was too far over) by turning the ignition to on postion (not starting it) and then within 5 seconds pushing the accelorator to the floor and up 3 times in a row (within 5 seconds).... giver a try. Cheers. Kennie

#89 of 116 Dash lights gone out by ptrent2 Mar 12, 2009 (6:33 pm)
I have been having an issue with my turn signals coming on barely then after a while they go out. The rear amber bulb stays on all the time til it goes out or corrects itself. Now that my turn signals are working my dash lights have gone out but the headlights stay on all the ime now. And when i get out of the van the chime is going off when everything is off. What's up any ideas on what may be the problem with this van. Any ideas are greatly appreciated. Replies to this message: jhirneisen (Mar 15, 2009 10:37 am) ck9show (Apr 29, 2009 1:39 pm)

Replying to: ptrent2 (Mar 12, 2009 6:33 pm) Sounds like it might be the common problem on this vehicle.......an electrical short in the rear tail light socket (pigtail). It causes various electrical feedback problems throughout the vehicle. See earlier posts on this web-site....diagnosis....repair, etc.. Jack Replies to this message: ck9show (Apr 29, 2009 1:39 pm)
#91 of 116 OBD2 LINK ERROR by jimjam3 Mar 28, 2009 (2:19 pm)
I cannot start my 1998 Montana. The motor rotates, but the pump does not spool up (no current going to pump) no spark on the spark plugs and when I connect my OBD2 scanner to check on any codes I get a "Link Error" message on my scanner. I checked the pump by jumping a positive wire to it and it'll work. I have a new spare computer and installed it only to get the same results. I have never gotten the "LINK ERROR" until now and I would like to know how can I fix it. Could it be a bad wire? Bad ground? I need to try to fix it and would appreciate any advice and/or assistance
