Question about 2000 Oldsmobile Alero

1 Answer

Power windows and blower motor stopped working at exactly the same time. At the power window circuit breaker (Right Junction Box) I used a bypass hot wire using 25A circuit breaker and closed the circuit to check my power windows and they all work just fine. So I know that all my motors and switches are good. I am not getting power to the circuit breaker in the right junction box. According to the wiring diagram pwr windws circuit breaker 25A is a Hot in Run only. I checked my blower motor with a bypass and thats good the resistor is good to. In the junction box under the hood I checked the blower motor relay thats good I checked terminal 30 (a hot at all times) And I have no power there. What do I do next? I'm really trying my best. please help

Power windows & blower motor quit working same time / 1991 dodge ram d150


Check the power window circuit breaker. Does it get hot to the touch? If so, it may trip till it cools off. Check for voltage at circuit breaker, probably goes hot with the key on. It gets voltage from ignition switch. Just to add, the fuse for the blower motor also gets ignition feed, goes hot with the key on. Whether everything is related, I don't know?

Power windows


First check the power window fuse and relay.
The fuse is located in the underhood fuse box, it is maxi-fuse G (30A) {actually its' a 30A circuit breaker}. Make sure that power is getting to the circuit breaker using a testlight. Also check to see if power goes through the circuit breaker by checking its' other terminal while a partner operates (or attempts to) the power windows. If power goes in to the circuit breaker but does not come out, replace the circuit breaker. (some circuit breakers reset after a while, but I'm assuming you've have this problem for a while, so you're past the time it needs to reset)

Power seat not working

Circuit Protection
Power is supplied to the seat motors through the 30A POWER WINDOW fuse. The fuse is located in the LH engine compartment fuse junction panel and is hot at all times. The circuit breaker is behind the interior fuse junction panel and prevents current overload and component damage.

Seat Belts/Front Seats


seats use heavy corrent & use relays instead of fuses. check relays in fuse panel. see chart on cover or owner manual for location.

Also, this is for 96 villager seats.
