This is a common problem which we have talked about several times on this web-site.
Could be two different problems..
1. simply a tail light bulb is burned out and causing a false reading in the computer or a power feedback.
2. but probably it's a short in the tail light fixture (pig-tail). The pig-tail supplier used a plastic that could not withstand the heat, so the black power wire is shorting out on one or more wires (in the pig-tail). You will need to remove the tail light fixture, cut out the defective pig-tail (smell the burned plastic, and view the melted female recepticals!!??), install the new pig-tail, be sure to use a di-electric grease in the new socket, install new bulbs and test.
Good luck.
This problem has been reported on the NHTSA web-site, but GM refuses to do the recall.

I need help with my 2002 Montana Key issue!!!!! by garvink

I have lost one of the two keys to my 2002 montana. I had a spare made and it will not start the vehicle. Does anyone know of a way to bypass the theft deterrent system so that the new key will work? My van is not really worth much money so i am not too concerned with it being stolen. If anyone has any advice or information i would appreciate it very much.
 
I think this is the correct place to post this.
 
Regards

Is the spare an official one with the chip in it? Also do you have one key that still works? If so feel free to send me an e-mail and I may know how to get it working

I have a 2000, and I just changed the oil! Warning light comes on saying time to change the oil?? I have over 2500 miles left on the oil change. Any ideas anyone? Also , I hear this happens alot with Montana, the gas sensor is broke. My needle shows full tank all the time! I heard eight hundred dollars to fix, so I will keep it full for now! If this has happened to anyone else, or you have any ideas on what I should do , please respond back. Thank you!!

1999 Montana Electrical Problem by losmorans

I doubt anyone is surprised by the title. Actually, my Montana has been incredible trouble free over the past nine years/70K miles. Yesterday the turn signals and backup light (driver's side) started acting up. The driver's side back up light is working but a lot dimmer than the passenger side. When I put the vehicle in reverse both green arrow turn signal indicators come one. The turn signals and emergency flashers work but the left turn signal hyper-flashes if I press the brake when it is engaged. I have replaced every brake, turn, backup, and license plate lamp/bulb in the front and rear. There is no visible damage to the wires/connectors. In addition, and perhaps coincidently, the ABS and TCS lights started coming on randomly on the same day. They clear with an engine restart. I checked the fluid levels and all ok. Any suggestions on either of these problems other than selling it?
 
Thanks - Dave

Edit : I did another site search - and it looks like I may have to replace a relay board... will see if my mechanic will do this for me.

Dave,
No surprise at all! Common problem which has been discussed several times on this site.
Basically.....tail light(s) plugs (Pig Tails) were sub-standard and cannot stand the heat of the bulbs. Pull out hear tail light fixtures, remove bulbs from recepticals and check for melting plastic, usually between the black wire (hot wire) and one or more colored wires. If so, cut out old Pig Tail, get a replacement Pig Tail, soder it in (I think about 6 wires), and use electrical shrink wrap around sodered joint, install new bulbs using Di-electric grease in the socket. Test before reinstalling light fixture.
Jack
