Chevrolet Repair: Chevy Truck Air Vents, chevy trucks, chevy truck

Question
94 Chevy 1/2 ton truck - I'm having trouble getting the blower motor to stay on.  The problem has escalated from having to jar the motor by kicking it, etc. to the motor not responding at all.  I have already replaced the motor, resistor and control module.  None of these replacements worked (luckily I got my money back for these parts).  My guess is that there is a short somewhere in the wiring but I'm unsure where to start as there are several wires behind the dashboard.  I've heard of other Chevy truck owners going through the same problem (using something to hit the motor to keep it going) and am hoping there is a well known solution for this.

Thanks for your help.

Answer
The next time it stops working make sure that it has battery voltage to the voltage supply wire and that the ground wire is also tight.


without actually performing the tests myself, I don't recall ever coming across any Chevy trucks with this fault.
