Heater problem
2001 Pontiac Montana 6 cyl Front Wheel Drive Automatic 150000 miles

2001 montana heater blower motor does not work. I checked all fuses and they are good. Tested for power at the motor connection and there is no power. Is there a fuse somewhere else other that the interior fuse panel or the engine compartment fuse block. The rear compartment heater is not working also, and the headlights will not turn on unless the switch is turned on. Would like to have heat in vehicle again.

It is a combination of fuses, relay and circuit breaker. As pictured, it starts with the 30A front HVAC circuit breaker, 25A HVAC Blower fuse, 10A Daytime Running Light/HVAC/Temp/and Heated Seat fuse (all these under the passenger dash), combined with 10A Radio fuse (I know, what gives), and blower motor resistor/relay combo (on the assembly) to power the front blower motor. Now it makes sense why your daytime running light not working.

For the rear, you will need the front to work for the rear to work, plus 25A Rear Heater/Temp Control fuse on passenger side fuse box.
