The piston is binding in the wheel brake cylinder, perhaps a bit of rust in the cylinder.
Inspect it, replace wheel brake piston and maybe the cylinder if you can't make it "smooth".
It uses a circuit breaker not a fuse . PWR/ACCY 30 amp . I would pull the power seat switch an check for B+ voltage on the orange wire an check the black ground wire . Using a DVOM - digital volt ohm meter . Circuit breakers very rearly good bad . There are two in the inside the vehicle fuse box . A - B ,the one for the seats is on the right ,this is A
check fuel filter remove and shake it and dump out contents on clean sidewalk to see debris thats been going threw it. other test would be fuel pressure . and common fails are fuel pump or crank sensor, try going to your local auto parts store like O reilly they usually have the best code scanners and it's free
Not blowing any air , hot or cold ?
blower is fine ???? How do you know the blower is fine if not blowing any air ? Doesn't work any speed ? High , low , med.
Blower motor , resistor or relay . Watch this video ! Do you have a volt meter , know how to test automotive electrical circuit's ?

Most likely a problem with the passenger seat sensor, BUT you always start by getting the trouble code from the computer. Otherwise you're just guessing.
THe 4l60 is an electronic produced shift trany, It sounds like the place to start, is to see if you can shift it manually. Starting out in first and work your way up as the vehile speed increases. I have a question for you. Did this problem occur all at once or over time? I would say most common reason is shift solinoid problem, But could be many other reasons like, sticking valve in valvebody, bent or worn linkage, improper fliud pressure to pistons, etc. with your help and imput we can probably narrow the problems solution down.
