How do you find a short in the dash?
I can tell you that having a test light instead of the blower motor can help out. Instead of trying to take the blower moter and re-hooking it back up have the test light over there and upon turning it back on, if the light shows and the fuze does not blow then you can have a short in the blower motor itself, if it does then try to route the wires. It would be easier to do that by the removal of the dash but that is work upon itself.
Could you be more specific? What isn't working?
Use a short peice of wire with an appropriate size fuse and connect the motor directly to the battery. If the motor turns, your motor is fine. If the fuse blows, your motor is the problem. If the motor turns,disconnect the connector from the back of the selector switch. Put in a new fuse and try it again. If the fuse blows you know that the short is before the power gets to the selector switch. Use a multi-meter to test for power at the connection to the selector switch. If you have no power at the selector switch something is wrong before the power even gets to the selector switch. If the fuse didn't blow move one to the next test. Use a multi-meter and check each wire with one lead of the meter at either end of the wire. They should all read very low resistances (less then 5ohms). If one of the wires reads "Overload" you have a broken wire. Now you need to check the wire to see if it is shorting to ground. Put one lead at one end of the wire and the other lead to the chassis ground. If it reads "Overload" the wire is not shorted to ground. If it reads low resistance, cut the wire at both ends and replace the whole peice of wire.If all this fails you can always try the penny trick. Put a penny in place of the fuse and look for the smoke. (JUST KIDDING)Get a good wiring diagram, start at the motor and work your way up stream back to the battery. Test each connection until you find the problem.Good luck, electrical problems are a pain in the butt.
check the fuses. These are usually located somewhere under the dash, Check your owners' manual if you cannot find them. I am assuming that all dash lights went out at the same time, so it is not likely that the bulbs all went bad. Many cars have have a rheostat that let s you dim or brighten all the dash lights -this may have gone bad. Finally there may be a short or bad connection…
I have a 1993 Ford Explorer XLT and when I turn on the headlights the fuse for the dash lights blows out do i have a short if so where.?
How do you find a short in an 95 Chevrolet pick up that blows fuse for th tail lights and dash lights when you turn the lights on?
Dash lights and tail tight inop on 93 suburban but the brake and turn signals work its not the fuse under the dash?
A short in the tail light circuit. Brake and turn are on another circuit. Dash light power is fed from the tail light fuse to the dimmer switch and on to the dash lights. Look for a short in the tail light wiring circuit. Also check the license plate light for a short as it is on the tail light circuit also. Had a car with blown fuse, traced the circuit for tail lights and…
check for a short in the wiring behind the dash or somewhere in that circut I had the same problem with my camaro it turned out that over the years the harness had rubbed on the plate over the ashtray and worn through the insulation causing a short, it took many hours to find and I eventually took it in to get it looked at because I couldn't find it
Unfortunately the question is "how long is a piece of string?" It depends on how easy it will be to find the location of the short, and how accessible that location turns out to be. It might take 20 mins to trace it and 5 mins to fix, or it might take 3 hours to trace, and 4 hours to strip out the dash to get to it.
