SOURCE: Clutch not disengaging when stopped at a stop sign for a period o

It is either your clutch master bleeding down, or your slave cylinder is leaking. Should be able to check inside the truck for a leak from behind the clutch master, the slave is by the trans.

SOURCE: No power to blower motor on grey wire

I would say the blower motor resistor has gone out. The front dash module or the rear one.

SOURCE: blower moter resistor works sometimes

You have a bad connection. more than likely a bad ground on the blower. Your A/C shuts down because of low suction pressure. The fan needs to be running and blowing through the evaporator.

SOURCE: Heater blower motor starts up

The brushes inside your blower motor are bad. You need to replace your blower motor.

Diagnosing an electrical issue is never easy or cheap, sorry. When fuses blow, it is due to an improper flow of electrons. When relays go bad, it is due to overheating(which is often due to an improper flow of electrons). The BCM(Body Control Module) could be to blame... let us know how it works out =D

DOOR LOCKS BLOWER DOME LIGHT GO OFF AND ON ENGINE STOPS ABRUPTLY

No it could not be haunted, you have a short to ground somewhere emanating from a terminal block where all of these systems come together, most likely near the firewall. This will involve tracing all of these wires. When a wire is shorting to ground it raises the potential difference of ground thus sending a lower voltage to various systems. The only other serious option would be your ecm computer, which is also very likely.
