Pontiac Montana Electrical Issues

  • I'm having a weird situation with my drivers side power window. It has a difficult time rolling down (very slowly until it's almost all the way down, but it rolls up just fine. Does it need a new motor? If so, why does it roll up easier than it rolls down? Thanx :-)

    I am having the same problem for about 5 years. Don't know if I want to go into the door. I'm suspect that the window is sticking on the upswing b/c when it is hot out it goes up faster, when cold slower. Also i've noticed on the montana that when the van is reving the window goes up much faster... as if power has something to do with it... could be a bad motor and it performs better with more juice. Let us know if anyone tries to fix this... just not worth my time going into the door, i've done so much more on this van - list something and i've likely fixed it myself.

    I recently acquired a 1999 Montana with less than 100,000 miles. It's in excellent shape, but there are some electrical issues.

    The primary one is that the indicator lights are completely wacked. When I signal, the lights flash quickly as though one was burn out, but they are not. When I step on the brakes, the flashing slows, but the brake lights flash too.

    Any ideas ? Is there a central control module that handles indicator & brake lights that can be replaced ?
  • To all of you that have had issues when you use your turn signals or brakes, or even in reverse: it is the connector to your rear lamp assembly - both sides. GM engineers (or de-engineers, as I call them) failed miserably on this particular model. I owned a 98 Venture - and currently own an 00 Montana - same van - same problem. The problem eventually would drain the battery to the point that it would not hold a charge: "parasitic drain" was the term used in an earlier post.

    I found a solution: went to my local pull-a-part and found a newer model (about 04 or newer) pulled those lamps off and replaced the old ones. It has completely solved that problem.

    However, the window motors suck and need replaced - has to do with the "de-engineered" system that lifts the window. I'm fairly certain that a lot of cleaning and a little grease in the grooves might resolve this matter.

    The starter problem that I am currently having is kind of weird. It worked perfectly for the entire time I owned it. Recently, it would give my wife issues: not engage the flywheel. She called it "just spinning and grinding". I took the starter to Auto Zone and it tested fine. Bought another one and it does something similar. I checked all the teeth on the flywheel and they are all there and not worn. It seems to me that the starter simply does not completely engage the flywheel. Was wondering if anyone else has had this issue and if they found a solution.

    starter issue you may need to shim the starter i had a pontiac sunfire that had a similar starter issue worked out great. gm shims can be found at autozone'
  • can you post a photo of the part you speak of or explain it better, i kind of get the picture but not entirely sure what you mean? "it is the connector to your rear lamp assembly - both sides." I am having this problem and need to fix it soon...my vehicle registration depends on it...and I am past due at this point as it is...thanks I don't wanna put time into fixing the wrong things....done that already....:(

    The problem relates to a poor design in the rear driver's side turn signal and brake light assembly connector. All 5 lamps use one terminal for ground. That terminal gets overheated and melts the plastic causing the ground terminal to get corroded. Cleaning the terminal will only fix it temporarily. replace the connector. you should be able to find a replacement connector on-line.
  • I am in need of some big time help. My 2003 Montana shows no power when you get in but when I lift the hood and unhook the fuse box from the stabilizer bar and move the fuse box around I can get it to start but once I put everything back to the way it goes, and turn the van off and try to restart there is no power once again.
  • I too had the slow passanger window, took it in and had it repaired but it didn't last long (about 8 months). I have had this problem since 2008. Good luck to all, as they get some milage on them they have more and more issues.
  • Good morning vondava3,

    I see that you had your window repaired but that the repair didn't last - was this done at a GM dealership or at another shop? When was the repair performed? We'd be happy to check into this further if the work was performed with a GM dealership - let us know via email at socialmedia@gm.com (include your name, Edmunds username, phone and address, the last 8 of your VIN and mileage, and the name of your dealership).

    Sarah, GM Customer Service

    The starter on my 2002 Montana quit a few days ago. Working 1 minute not working the next. I took it off and had it tested at a local parts store who confirmed it was bad. I lose all electrical power. I bought a rebuilt starter brought it home and installed it. When I tried to start the van, again nothing. In addition I lost all electrical power. nothing electrical is working.
    the battery is good and fully charged. I rechecked the connections to the starter. Checked all the fuses, Both under hood and dash mounted and they all appeared ok I am at a loss. Has any one else experienced this or does anyone have any ideas on what could have caused this total power loss?
    Thanks,

    starter fusible link, relay main fuse blown, is there power to the starter?
  • bix49bix49 Posts: 5
    Yes, there is power to the starter but it's not associated with turning the key. The starter begins making a whirring sound when I attempt to reconnect the positive battery cable. The negative cable already being connected. I will again check the fuses and look for the fusable link you mentioned. Am I correct in thinking that the fusable link is on a separate line that connects
    to the positive side of the starter along with the cable from the battery? Also does the fuseable link do more than protect the starter circuit? I will look very thourouly for a blown main fuse. I have been thinking that there's just one thing that has caused all the power to the vehicle to go out. I'll write again with my findings. Thanks for your suggestions.

    Well, I think I'm closing in on the problem. I tested all the relevant fuses and they were all good. It was getting a little cold by the time I finished so I wasn't able to get to the fusible link which I'm now pretty sure is causing the problem, at least with all the electrics except the starter. I hate to admit it but I believe I incorrectly reconnected the wires to the solenoid. If you're still out there labrat68 let me ask you this. The cable from the battery connects to the post on the solenoid that has the cable running into the starter. Is there another line that also connects to that post. The line with the fusible link? Once I know that I think I can get things working again. One more question. Could mis-wiring the starter like I'm pretty sure I did, damage it and cause it to malfunction. This is the second rebuilt starter I bought from the same auto parts store where the solenoid does kick the Bendix gear out without spinning it. Although it could just be my bad luck.
    Any input would be appreciated.
    Thanks,

    Hello, I've got a problem or maybe 2, with my 2002 Montana that I hope someone can give me some advice on, because it's driving me crazy. I replaced the starter and when I tried to start the van, nothing happened. I had cleaned all the connections prior to installation and made sure that the connections to the solenoid were correct. All fuses and relevant relays were checked and all were good. The battery was at full charge 12.6v. When I turn the key to the start position I can hear a click from the relay but the purple wire at the solenoid showed no power. I finally got around to jumping the starter and the van started. Checking the dash I found the battery light on. The battery was not being recharged. After a lot of reading and some phone calls, the conclusion I came to was 2 possibilities. A burned fusible link or 2? Or a bad neutral position switch. I haven't found the switch yet but the 3 other wires besides the battery cable that attach to the solenoid all appear to have fusible links. They all "appeared ok." I pulled on them and could detect no streching and I didn't feel any soft spots, but is is a little cold here and the wires are pretty stiff. Do you think I'm on the right track and what do you think I should do next? Any advice would be greatly appreciated. Thanks, Bix
  • I failed miserably on following up with everyone. I did resolve the starter problem. I purchased a rebuilt starter and got the same results: starter just whirs, completely missing he flywheel. A friend suggested I return the rebuilt starter and pay the difference for a new one. Took the rebuilt one back, tested it to be on the safe side, and it tested fine. I installed he new stater and voila, it started right up. Had no problems with that ever since. Has something to do with hear shroud not set to properly engage with the flywheel.

    HOWEVER....the engineers do not just fail on the lights, fuel pump, and the windows. They really messed with the stupid 3400 engine. If you start having overheating problems, I know the proper solution: junk it. It costs way too much to replace the engine, and repairs are never forever. It seems the water grooves and the oil grooves run side by side. After several years, the thin sliver of steel that separates them wears out, allowing oil to infiltrate the cooling system, and vice-versa. The only sure way to repair this is to replace the engine. That is about $1500 to $2000, depending on who you get to rob you.

    All I can say is that the Montana was a good little van, took me all over the country, until the overheating thing started. Then, it was a short 4 months until I finally sold her to the local pull-a-part. Anyway, happy mechanic-ing.
  • Hi all. I bought my 2003 Montana new, and I have loved it for most of its life. Lately, though, I'd say in the last 2 years or so, I've started to fall out of love with many aspects of the electrical system. First, the dvd player stopped reading most of our dvds. We replaced the dvd system at the dealership, but it is still having the same problems. Then the clock display light went out. Then the driver side window started dragging when I rolled it up. The passenger side window can't be controlled by the driver side controls anymore. The traction system went out. The oil light is perpetually on...even when I get the oil changed. Within the last week, I start the van, and the radio changes to a different BAND. I have to press the BAND button to put it back on the radio. I have less than 68,000 miles on it, so I haven't driven it into the ground by any means. Any suggestions for this teacher who has little money to spend on figuring out and fixing the problems? :cry: Thanks.

    I recently had to disconnect the battery in my 2002 montana, and since the radio has the safe guard feature I though I would be writing about the codes just to get the radio to work. when I reconnected the battery the radio turned on fine. I didn't even lose the presets. I did have to reset the clock and now every time I turn the van off the clock goes back to 12:0Thanks,0. Anyone have any ideas?
    Thanks,

    Bix
  • The van ran good and we parked it for a few months. We try to start it now and with a good battery everything is dead. No lights, no horn, and when you try to start it all you hear is a click. The motor will not turn over.. we have tried jumping it and still same thing happens. Would appreciate any help or direction someone could give me..
