blown fuse

[Glenn]

o.k. I got a fuse cover from a junkyard and it was the cigarette lighter fuse. The cig lighter was loose and falling apart so I just removed it. I put in a new fuse and turned the key on and abs light went out and fan blew but I couldnt check windows because I still had the door panel off and wires unplugged. I thought o.k. so I put door panel back on and started car. ABS light back on , windows dont work, fan doesnt work, BUT fuse is not blown anymore. Any other thoughts?

I have a 2g, so I don't have the owner's manual for your car. Did you check every other fuse? Guys w/ 1g's, please help this guy out and look in your manuals.

Sometimes a circuit will go dead instead of the fuse blowing. I have seen this many-a-time. Tell me, do you have power at the cig lighter wire with the key on and the fuse in?

[Glenn]

I do have power at the cig lighter wires. I am now thinking it is 2 separate problems. The lighter and 15 amp fuse is fixed. There is no power to the window switch, no power to the blower motor either. I checked the turn signal switch per the haynes manual and it is working. I am guessing there is a fuse,relay,circuit breaker, somewhere under the dash, but I can't find any. There is a box under the hood in front of the drivers side on the firewall with a/c fuses and relays. I have power there.
Thanks for any suggestions.

Check for power (with the key on) at the accessory wire in the main ignition harness. Wire Magic does not list a 91 Eclipse, but the color is blue/black for a 91 Talon. If you don't have a blue/black, poke around with the key in the acc position. If don't get a wire that is hot only in the acc position, your problem lies within. It is fixable.

Thanks for responding! I have the dash completely apart now so it is easy to get to everything. I have a blue/yellow wire in an 8 pin connector that goes to the ignition switch. It has 12.09 volts with the key on and zero with the key off. I have spent 3 days straight on this but I will figure it out!
Thanks

Keep in mind the key's position. There are 4: lock, acc, run, and start. Look for a wire in that harness that gets power in ACC. If you cannot find one, that is your problem.
Does the radio work?

[Glenn]

Radio works fine. I do have 12 volts at the blue/yellow wire when the key is in acc. Here is todays results. Someone suggested power for my problem circuits has to run through the ignition switch so I replaced the ignition switch, ignition key cylinder, and the combination switch behind the steering wheel. I know have turn signals again, so still no power windows and no a/c vent fan (no compressor either).
Thanks for responding!

Is anyone good at reading wiring diagrams. My haynes manual shows power going through the ignition switch (ig2) to the power window circuit and also the fan blower circuit. I think my problem might be in there. What does ig2 mean?

[alanseijas]

That means that there are 2 ignition wires. An ignition wire will show ground when the key is off, ground while the key is in accessory; but will show positive when the key is in the run AND start positions. Does your manual give a color?

[Glenn]

It is a blue/black wire. It has power at the plug in connection at the base of the steering column. I am now guessing there is a short/break in the wire after the ignition switch but before it goes to the windows and fan switch. Unfortunately the wire goes into the huge harness that is all wrapped up so it will be pretty difficult to track down. Thanks for your help, i'll keep posting with info until it is fixed in case someone else has a similar problem.

Remember that you can always cut the power supply wire to your power windows, and run a new one. The blower fan is more difficult because of selectable fan speeds.
Try this: Run a power wire to your window motor's input wire without cutting it, and see if your blower fan powers up too. They may run off of the same dead circuit. If this works, I will give you a wiring schematic for a permanent fix. Let me know.

[Glenn]

It is fixed!!!!
I checked each wire in both circuits and all had continuity. I then worked backwards from where I could detect voltage and found no voltage coming out of the fusebox from the number 3 10 amp circuit. The fuse was fine and was not blown. It had power coming in and not going out so I pulled the whole fusebox out and took it apart. One connector on that circuit was "loose"fitting. I pulled a connector off of a spare circuit and swapped them. Thanks for all of your help.
Remember, even if a fuse is good power will not travel through it unless it has a solid connection.

Nice work Glenn! Want a job?
