Any chance you have loose "fan" belts, they may be slipping and it smells like burning rubber? Or could be a bad coolant leak if the smell is like antifreeze, so not enough coolant to get to the heater coil. Have you checked your coolant level recently?
And perhaps all fluid levels need to be checked. Have you had it serviced by a competent well recommended Mechanic at the recommended service times?
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: where is the bcm program fuse on a 2005 pontiac montana sv6
The BCM program fuse on a 2005 Montanna SV6 is called something different in the manual. It's called a “Keyless Entry Module” fuse and it is fuse #7. The fuse panel is located on the passenger side on the side of the dash. There is a cover with an indent hole in it to pull the fuse cover off. It's really hard to pull it off and it almost seems like your going to break it when your trying to get if off. Keep pulling, it will come off! On the fuse cover, fuse #7 is labeled " RFA MDLS" which is again different than what is in the manual. I followed the procedure to reprogram my "Key Fob" and within 45secs, I had reprogrammed my key FOB! I was so excited, because, I have been trying locate the BCM fuse for 4 weeks. I think GMC does not want us to know it’s location or name, so you would have to go into a dealership to get your Key Fobs reprogrammed costing about a $100 for a minute of work.
1. Keep the windows open as a safety measure, then,
2. Remove the ignition key from the ignition lock cylinder.
3. Remove the “RFA MDLS” (fuse #7 ,BCM PRGRM fuse, Keyless Entry fuse) from the fuse panel.
4. Close all of the doors.
5. Close the liftgate.
6. Turn the ignition lock cylinder to ACC.
7. Turn the ignition lock cylinder to OFF, and then back to ACC within 1 second.
8. Open and close any vehicle door. A chime will be heard when the system enters the BCM programming/diagnostic mode.
9. Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for 14 seconds.
10. Important
After 7 seconds, a chime may be heard confirming successful programming.
11. Repeat the previous step on each additional transmitter to be programmed.
12. Remove the ignition key from the ignition lock cylinder
13. Install the “RFA MDLS” fuse ( fuse #7 ,BCM PRGRM fuse, Keyless Entry fuse) back into the fuse panel.
14. Press on the key fob functions (EG. Lock, Unlock) to verify correct operation.

SOURCE: Where is the fuse box for a 2006 Pontiac Montana
on the driver side under the dash or the side by the door jam
SOURCE: I own a 2006 Pontiac
probably the blend door not opening fully. Do you hear a clicking under the dash by passenger's feet? If not, try calibrating the system:
If this doesn't work, your actuator may have failed. Look under the dash to see if any of the actuators on the heater box are trying to turn when you change the temperature setting. Unfortunately, I cannot find aftermarket parts for your heater, so if the door isn't working you may need to go to the pontiac dealer. Let me know if you have questions.
