SOURCE: real right turn signal light - Pontiac Montana SV6 2005

If the 2005 Montana is similar to the 2001 Montana, I have a solution. First you'll need a hexagonal wrench (the 6-sided L-shaped wrench). The tail light assembly is held on by two screws. You'll need the hexagonal wrench to remove them, because a normal screwdriver won't do it. I also had to use a conventional adjustable wrench to get the leverage to turn the hexagonal wrench, because the screws were in there pretty tight. Once you remove the two screws, the whole tail light assembly should come off. Mine required a little force and I had to play with it a bit, but it came off without a lot of work. There will be one set of wires that connects the tail light assembly to the rest of the minivan--try not to damage that set of wires. Once you get the tail light assembly off, you'll have to take apart the assembly that actually holds the lights. No tools should be required. It's held on by four plastic catches. Just undo the catches (easier said than done, but still not too tough) and it comes apart. Then you can pop out the old light and pop in the new light. Then re-assemble. For me, it went back together much easier than it came apart.

SOURCE: 2005 Pontiac SV6 Montana key fob unlocks doors but will not lock

For the sliding doors you need to clean the contacts, there are 6 or 8 on both sides, just wipe them clean as they are probably covered in oil/grease/grime.

SOURCE: 2006 Pontiac montana SV6 power sliding door sensor

I have a 2006 SV6 with the power sliding doors. The problem that I found was with the contacts on the door ( They are called plungers) the movable pins were losing connection with the fixed part The plunger is very easy to replace if you can find one. The plungers are covered with a rubber cover and is held in place with 2 plastic pins. My Pontiac dealer could not even find one in his books or even a picture of one, and claimed that he had never had anyone come with a door problem. My Chevy dealer said that it came with a wiring harness that is not needed for $154. The cure that I came up with was to take the plunger block apart (it snaps together)and replace the rusted out springs then solder 3" wires to the end of the plunger pins (they solder easy) to the tabs that go to the plug(pop out the tabs or you will melt the plastic. It took about 45 min. now the doors work like new and will never loose contact again

I had a similar problem with my 2006 Montana. It ended up being the foam shield donut looking thing that stops the parking brake cable from hitting against the middle of the rear axle. Fixed it with foam plumbing insulation and electrical tape. Better than new. Hope this helps.

2006 PONTIAC TORRENT WON'T START CODE READS COO4O ONLY CODE STILL WON'T START


C0040
Right Front Wheel Speed Sensor Circuit Malfunction
EBCM
DTC C0035-C0051

The wheel speed sensor produces an alternating current signal whose amplitude and frequency vary, depending on the velocity of the wheel. The electronic brake control module (EBCM) uses the frequency of the AC signal to calculate the wheel speed.

This wouldn't have anything to do with not starting ! Won't start how ? When you turn the key to the start position what happens ? Does the starter engage an spin the engine ? This would be a crank no start , now if nothing happens when you turn the key this is a no crank - no start .

Service ABS and traction control systems is displayed in my 2005 pontiac montana sv6. New breaks have been installed and lights and system still on. Scanned and shows no sign of sensor issues


well this is a sensor problem. just cause you didnt get a fault code dome mean that the sensors are ok. Remove the abs Fuse from the fuse box under the hood. Drive the car and get a feel for the braking. Replace the fuse and drive again, you will notice one or more of the wheels dont hold as it fast or faster than the rest. Replace that sensor.

Just bought a 2006 Pontiac Montana SV6. The dash display said, "check traction system" and "check stabilization system," so we bought it "as is," to fix it ourselves. Our...


the check stabilization problem sounds like ur ride control meaning ur air shocks in rear leaking or faulty compressor. traction control is possiblt an erratic reading from one of ur 4 abs sensors/or rings,anyhow u need to get ur computer system scanned for a more accurate fault description and possibly fault codes which will b very important in solving ur issues. good luck

you have a sensor per wheel, you need a scaner to read each wheel speed.one not working.
