Question about 1992 Dodge Ram 250

1 Answer

No power to windows or heater and a/c switch

Window switch will not close window and heater fan will not turn on fan. Checked fuses and found only one 15amp fuse bad, but that was not the problem. I was trying to locate fuse diagram to troubleshoot.

I had the same problem a few years ago on a converted '92 Ram B250 van. Turned out to be a blown fusible link in the engine compartment, under the hood, right next to / behind the brake master cylinder. These links were used instead of fuses up until '92, so it is likely the problem you are having as well.

1998 Oldsmobile Cutlass, sunroof is stuck open and it goes back and lift up but it won't shut. Cpuld it be a fuse? If so wheres the fuse located?


When pushing close switch?
are any sounds from switch,
is any movement to window,

The fuse can be found in one of two places. Fuse box on driver side lower dash by driver door.

Relay Fuse Center, under the hood, upper driver corner.

A bad fuse would cause NO POWER to sunroof. IF window moves back and up, fuse is good. Cause for not closing, or moving forward would be wire connection to forward/close switch, or a bad switch. Also could be window track.

Checkand clean sliding track, window could be geting stuck on something.

Check wiring to switch, this means pulling the switch.

After changing the battery in our 02 PT Cruiser,the air bag warning light came on and won't go off along with the power windows/fan motor/ rear defrost stopped working. car starts and runs fine.


Year/make/model???? Changing the battery should not affect all of the above. Sounds like a power supply issue and possible ignition switch problem. Try starting the vehicle and gently moving the key/ignition switch back and forth slightly while using the window button and heater fan on. If these begin to operate while moving the key, suspect an ignition switch issue

How do I find the wires to trace why heater fan not working on 1989 Isuzu elf 150


The color of the cable at the switch should be the same color at the fuse box > All ways check fuses with a test light they can look ok but be open circuit.

My 02 nissan pathfinder interior fan runs even when not turned on.checked all fuses they seem to be fine.


If fan still runs when all your heater control knobs and buttons are off, it is likely a bad heater fan switch. Unless you have something like a body control module found on newer cars that has some control over interior functions. If not, try a new heater fan switch. Good luck.

I was rolling down a window when all of a sudden the follow 4 things STOPPED WORKING and haven't worked since: - All power windows - Heater blower - Horn - Wipers All of the relays I've found seem in tact...


Is the car a convertible? If so the window controls operate through the convertible top computer.
By ignition switch module are you talking about the part under the lock cylinder? They do fail a lot.
What do you mean by the relays are intact? Have you checked for power at each fuse with the key on?

99 Malibu-cruise, power windows and fan blower aren't working. Found fuse panel on passenger side of dash. All fuses are good. How can I fix the problem?


Have you checked the fuses in the under hood fuse box? Sounds like you have a blown Maxi-fuse or a bad ignition switch.
