Few issues,
I keep blowing the fuse for the back up lights, i disconnected the multi switch and checked connections all looked good. I pulled off the tail lights and check bulbs, and changed them. Still blowing fuses, i tried a bigger fuse and blew that as well. I tried pulling the trailer relay but nothing changed. Other problem is that the wipers don't go back to home position. Kind of lost here does any body have any suggestions |
Wiper not returning is wiper relay board &/or wiper motor. I'm going to change the whole thing as a unit & use the warranty. Board alone is cheaper but it will likely burn out again the next time wipers get stuck by ice.
Blowing fuses is a short to ground. Disconnect circuit loads & test for ground. Google turns up much info. 01 FSM is available for free download & may approximate the 02 headlight circuit. |
I have traced all wires and came up with nothing, at one point it took a few days to blow the fuse, know it blows as soon as i turn on the key. The only thing that i can think of that changed was i took out the light switch and unplugged and re plugged back in, Could it be this switch????? I have heard that the trailer package could effect the back up lights, Wipers still not returning to home position should i just change the motor or try replacing relays.

General short finding has been discussed a lot. Easiest thing is to google parasitic drain. Lots of step by step instructions. You'll want a diagram.

Wipers and back ups are not connected in any way. There is a write up re Wiper motor rebuild on this site. Try searching it.
Back ups are ground switched. THey are hot wired and the switch completes the circuit by providing a ground. Is the fuse blowing upon insertion or when you go into reverse? |
when the key is off it is fine, as soon as there is power the fuse blows. As stated above, when i first discovered this the fuse would not blow right away now it does

If a circuit blows a fuse, you have a short, excessive load or an undersized fuse. Connect an ammeter and disconnect loads until you fine what is pulling the amps. Be sure your ammeter is fuse protected. The process & concept are easy. Finding the cause may be a pita. On Datsun Zs, it is frequently the bulb socket that is grounding. How did you test? What else is on the circuit? A wiring diagram will be useful. Good luck.
