I have a 1989 IROC 5.0 TPI. I currently have no Horn, interior lights, and the trunk release button. Everytime I put in a fuse in the accessory location it blows instantly. Any ideas? I recently had the alarm taken off hoping that would fix the problem but no luck. It seems like a direct short. has anyone had this problem before, is this a common for this car.

 

i had this problem recently with my gauge fuse, but it was because i had something else plugged into my fuse box. if you do have anything else plugged into your fuse box take that out then try a new fuse

 

what do you mean? what did you have plugged in?

 

i had a power wire hooked up for my speedometer converter, but anything you plug into the box at all could possibly effect the way other fuses work

 

This is the darndest thing, but check your cigarette lighter outlet. I had a penny down inside mine when I bought the car Take a good look!

 

could be the cigarette lighter itself... disconnect it then try

 

thanks guys. I will try that tomorrow. I just put on the SLP intake runners and a ac delete pulley, removed smog pump and did the coolant bypass upgrades yesterday and today. not to get off the subject, put these upgrades made a huge difference. so I am going to tackle the cig. lighter trick ans let you know. I hope that is what is causing this fuse problem, I will be one happy dude if that is all I have to do. I am still up for other suggestions.

 

man you guys are good. It was the cig lighter, I unplugged it and instantly the short was fixed. thanks a million. I was getting to the point of taking it in a a ecectrical place, so you saved me a few hundred bucks! Thanks again you guys rock.

 

I always knew smoking was a killer, and in this case in more ways than 1

 

Glad to be of service!

 

good one.... but really, thanks 4 the tip on the cog. lighter. I took 5 minutes to fix a 2 year problem and almost 1 accident from having no horn due to acc. fuse always blowing. Thanks again guys! Have a gr8 Easter, you better go to bed so the easter Bunny will come.

 

I know this is an old thread but I must say after countless hours of trying to fix the same exact problem I was getting desperate and thinking of taking the car to an eletrical shop. I know of other third gens that not only I have owned but other people own that have this exact problem. Just wanted to say thanks!!!

P.S. this should be a sticky in the electrical tech. articles........

 

I HAD THE SAME PROBLEM. I EVEN REPLACED THE CIG LIGHTER SOCKET WITH A NEW ONE. EVERYTHING WORKS FINE UNLESS I ACTUALLY USE THE LIGHTER AND THEN IT BLOWS THE FUSE. I JUST QUIT USING THE LIGHTER AND NO MORE PROBLEMS. WORKS GREAT FOR THE GPS AND THE CELL PHONE CHARGER.

 

Damn, I guess I know what I'm checking. Mine is doing the EXACT same thing, except I have a 4th gen center console... I hope this works...

 

haha, I think I might have swapped out the original 3rd gen cig lighter. I disconnected it and everything works great! I'm glad I didn't have to spend half a day doing and undoing the wiring!

 

YEAH, WIRING DIFFICULTIES MUST BE ONE OF THE MOST FRUSTRATING THINGS ON EARTH! GLAD WE HAVE THIS SITE TO COMPARE NOTES AND EXPERIENCES. COULD SAVE US HOURS, IF NOT DAYS, OF HEAD SCRATCHING.
