02 buick rendezvous no heat
sounds like heater core went out or is stopped up. Is the floorboard wet on either side of the car? Either flush the system with a cheap kit for about $25 or look at getting a new heater core. Usually these are behind the dash but usually easy to get to.
The engine is running fine but I can't move the truck. it's as if the wheels locked up.
There are several things to check. I would lift one wheel off the ground, at a time. See if one or more are frozen. A frozen brake caliper or defective/damaged emergency brake system could cause this. Have you verified that the transmission is engaging and not slipping? Please let me know how you are making out and if you have other details or questions. Good luck.
Engine coolant sensor code
If you would like to share the codes with us we may be able to help.
Its not likely the cooling system would kill the engine tho unless the sensor is signaling the engine is too hot.
Dash lights
I guess you could say there is no fuse for the dash lights.
The dimmer control on the headlight switch actually goes thru the body computer and the dash lights get their power from there. The body computer has several fuses involved. The other interior lights not controlled by the dimmer get power from the park lamp relay.
Cooling system
check fuses and wiring. Remember that the fans may not work until an operation temperature is reached that switches on the sensor.

Have the fuel pressure tested. If it's low from a tired, old pump, you know-new pump and new fuel filter. Low pressure also causes hard starting.
