electrical problem help

[davos77]

I have a 94 GT and for some reason I keep blowing fuses to my tailights and brake lights . I also have the air bag light stuck on and the odometer doesnt work . I just bought the car about a week ago and have had it in the shop since then trying to resolve this lighting problem and I need some serious help with this .

this website now has 94-95 color wiring diagrams on it and one is all the lighting........

The same site (that Tom listed) also has air bag info.
For tracking down the short in the lighting, post more info about the circumstances required to make it blow the fuse (only after you apply the brakes for the first time after fuse renewal, etc. Ditto for tails).


:OT: Tom, I was going to PM you and thank you for the GREAT diagrams - I only found the new 94-95 ones two nights ago.

I'll keep adding as time alows and I get uncolored diagrams. BIG Thanks to Stangplus2birds for being so reliable about keeping the site up!

It's usually something very simple when it comes to fuses blowing. Get an owners manual or look at a chilton and find out all the devices/circuits that are shared with the lights you described on the same fuse. Then trace down each one of those. Broken circuits or shorts don't usually happen inside the looms so it's not too difficult to find them.

Thanks all

I am blowing fuse in the underhood compartment Marked (INT LPS) and it only blows when I am driving , at idle while car is sitting still the taillights and turn signals work fine . Could it be a bad turn signal switch causing this to happen ?

Fuses 9 & 5 circuits have nothing in common other than front park/turn and the rear park/stop/side marker bulbs and bulb sockets - it they are blowing at the very sane time, you may have a bad bulb or bulb socket.

Yup. sometimes when a bulb blows it can creat a short.
