this truck is a 2000 npr Isuzu , quick and easy way to trouble shoot your blower motor. could be hot wire, ground wire, bad blower, or resister. 2 min to test them all. enjoy!!
Isuzu NPR with a mounted box food delivery body. Driver said A C just stopped working Monday when he got in the truck; I test drove the truck Saturday after replacing the rear brakes and the ac worked fine. I hooked up the gauges and had no low side pressure and 50 psi high side.
