Accessories don't work in "On" position
After leaving my car parked in a parking lot most of today I noticed
while driving home that my radio would go out for just a second when I hit my brakes. I then stopped to get gas and my seatbelt wouldn't move forward (I have a 1993 Mitsubishi Eclipse). After getting home and testing I found that some of my accessories won't work when the key is in the "On" position without the car being started. The windows don't work, the seatbelt won't move with the door being opened, and my radio doesn't work. However my cigarette lighter and air conditioning both work when it's in the "On" position. What could be causing this? Any help would be appreciated. Thanks, Chris |

On vehicles from the rust belts, I would immediately think rotted or
broken body ground strap. There should be some kind of mesh cable going from the engine to the body or a black cable going from the battery negative to the body. If that body ground is bad, you will get symptoms like yours. One test is to use a booster cable from the battery to a ground spot on the body to see if things start working or if what works changes.

I recently (about a month ago) had a bad alternator replaced. I was wondering if driving the car tomorrow will be ok with the fuse blown before I can go to get a new one? Thanks for your help, Chris |

I got lucky and found a replacement at the one local auto parts store and changed it out. It works fine now. Thanks for your help, Chris |
