you will need to pop off the b-pillar panel and remove the retractor assy. what I usually do is pull the belt all the way out and blow any dirt/dust out of the retractor and spray it real good with silicone spray to lubricate it. Or replace it,but I've had good luck cleaning them.
The first thing to do is make sure you have the correct part number for vehicle,then verify none of the pins at connector have had heat damage/corrosion,then verify good continuity of the circuit,and final you'll have to test the switch.
You will need to hook up a scan tool and retrieve codes to see where you need to start your pinpoint testing. Although you can get this done for free at some auto part stores,do not let them sell you anything without getting expert advice on it first!!!
I agree that a good check of the hub bearings might show the problem.
I would begin by scanning it to see if it has codes and if communication can be made with the engine control module. a good thorough check of all fuses wouldn't hurt either along with a quick visual inspection.
are there any aftermarket electronics like a stereo on the car? have seen short to power before cause this from bad install
I'm guessing that you're talking about the powertrain control module? If so you'll have to do a programmable module installation so that you can put the vehicle info into the new module. A dealer is the only one that I know of that can do this,unless an aftermarket shop can handle it.
between 1 to 1.5 hrs plus the part,i'm guessing 100-150 bucks.
check the cable for the temp control door,check temp of heater inlet and outlet hoses and verify that heater core is not clogged.
you really need to get it professionally scanned so they can see what's going on and figure out the root cause of your concern. It might just be a vacuum hose leaking which wouldn't cost much to repair,just don't go to autozone and let them sell you something you don't need,I've made a lot of money on parts stores misdiagnosis.
