Blower motor dead, 2000 Impala
2000 Impala 3.8l ----Old Fan blower motor was very noisy... replaced it with new one that I tested on bench (runs well). Won't run in car. . Old motor never would run on anything but hi-speed.Tested plug to fan, No volts any position on fan switch. Pulled the two 25a fan fuses, tested ok with ohm meter, and fuse sockets have 12vdc on right side. Swapped fan cont relays, no change.Then tested all fuses in both boxes, all OK. What's going on????
Any body got any suggestions of what to do next? I would greatly appreciate it.
I don't want to take it to the dealer unless as last resort.
Tx, Ted without defrost in Maine.
