1992 Dodge Dakota blows 50 amp fuse under hood when started. Runs fine when started, but several items, such as windows, locks, A/C fan don't work.

Roger it sounds like the blower motor is not comming on. There is a resistor network located in the engine compartment on the passenger side mounted to the firewall, that controlls the blower motor. The connections may have corroted or the unit itself is bad. That was the first thing I had to relpace when I got my used 92 Dakota. There is also a 30 amp fuse in the fuse box under the dash board . If that is blown I would suspect the blower motor is seized up or just pulling too much power.

i don't know does that help

I had the same problem after a weekend trip, I found that the 50 amp fuse in the fuse box under the hood was blow, this other things that stopped working with this was the seat wouldn't adjust, the seat heater wouldn't work, and when we locked the car it wouldn't beep. When searching for the problem I found that the tube going to the window washer in the hood was broken at the hinge and while working on this the short at the fuse location went away and everything started working. I read that the problem was the heated window washer nozzles that were shorting out, if this happens again I will be unplugging them. Now that I fixed that problem the airbag light has came on and will not go off.

Have you checked the blower motor resistor. Usually locate in the blower box with a plug on it. Has 2 bolts holding it in. Take out and inspect.

Maker sure your flasher is ok and that you are getting power you will have to trace it from there

try the blower motor

Check under the hood at that fuse box there should be a 40 amp fuse in a slot marked "run ign" or some such thing, for about $3.75 if you replace that fuse it should start working again, this just happend to me a month ago.

Regulator in alternator obviously faulty, have it bench tested & fixed or replace alternator, and cure your problem.

THE FUSE IS LOCATED IN POWER DISTRBUTION CENTRE UNDER HOOD. THERE IS ALSO ARELAY IN THE SAME LOCATION.

UNDER THE HOOD ,,DRIVERS SIDE, BLACK BOX,, ARE CIRCUIT BREAKERS,,, 50 amp breaker goes to headlamps,, 50 amp goes to blower motor, switch those breakers around and problem is solved...
