Which circuit do you need ?

I think u need to replace "air mass sensor" normally when it's broken cars taking lots of gas

First start by establishing that you have power it the switch. If so move to the back and see if you get power there when the switch is thrown, If you have power bring a ground wire and touch the case of the blower. If it runs install a new ground source. If remove the blower motor and field test it. If it fails replace it. Nothing will happen unless the motor runs. Remember the front unit must be on so the back will cool.

check the door switches for a short

Had this problem for some time. I have had the dealer replace motor etc. Problem still returns. Noticed that the foam seal around the right side door has started flatening out over time and was beginning to spill into the lipped plate that the door sensor buttons possibly could be prevented from making proper contact. Trimmed approx. 3/8 of an inch off the foam in the area of the plate, and the problem seems to have gone away. Hope this helps.

If you checked wheel bearings,and they are ok I would check rear sway bar links.they will cause a knocking sound .good luck!

air in the system is the cause. look for a leak of coolant and i would check the intake first.

There is no drive shaft in your Montana, it is front wheel drive.

unfortunately the fuse that runs the chime also runs other items on that circuit so pulling the fuse isn't an option, basically what you need to do is check each door switch , one is shorted, and is in the open position,, they are located at the side rails of each door, remove the deco rubber trim, and you will see that a screw holds them on, they pop right out, with a meter, check each switch for continuity with the switch in the OUT position, when the switch is depressed, you should get no reading, since that closes the circuit, you can either replace the bad switch, ( sometimes they just get stuck,m so move them around and spray some electrical contact cleaner on each one) BY the way,, on this model of vehicle, there have been a number of issues with the sliding door latch ,, here are some of the issues ,, http://www.lemonlawclaims.com/Chevrolet_uplander_sliding_door.htm

About the only thing that the headlights and turn signals use together is the ground circuit. They get power from two different circuits.Could be a ground problem in the harness or one of the connectors.
