It appears the 92-94'* are different. Over $100 with twilight sentinel & around $35 without. Does the switch for your 95 have the twilight sentinel module on it?

Well here'* a possibility... I found today that if I turn them on with the key on, not started, it blows after about 10 seconds, but if the car is started, it blows as soon as its turned on. But here'* what im thinking... What about a relay? If the relay is stuck on, it will pop a fuse. I've had it happen to my mom in her Buick.

I thought you would have bought a switch by now. Why don't you drive over to the local auto parts store, explain your problem & see if they'll let you try out a new switch. I'd just go with the non-sentinel version. That twilight sentinel really looks like a serious fire hazard. It sounds like your lights aren't coming on automatically anyway. Billboost asked why you're turning them on manually but you never answered him.

If you remove your switch you might be able to remove a cover from the module & see if the circuit board is fried. While the switch is out you could try using a fused jumper to turn on the parking lights. You'll need to know which terminal is the power supply and which is for the parking lights.

Nope, the twilight sentinel is fine. It is only the parking lights. Only that fuse blows, nothing else. I bought a switch off of Ryan here on the forum. I should be getting it here soon.

So your headlights & tail lights are coming on automatically when it gets dark?

Yes they do, but as soon as they come on, the fuse pops for the parking lights. Twilight works. I drove it home with the twilight with no parking lights.

I think that makes it less likely that the switch is the problem but lets see what happens when you get the replacement.

Edit - Hey, what size fuse are you using?

Stock size. 15 Amp. I don't even want to attempt a higher, so I didn't.

I wasn't going to suggest going to a higher amp fuse than what is called for. I've got a Chilton'* manual for 88-93, some years use 15amp & some are 20amp. If you're using too small a fuse & if your battery is on the weak side I could see how starting the engine would cause the fuse to blow right away. I'm now wondering if the correct light bulbs are being used & or if there is moisture in any of the light sockets.

Well, we did find some moisture in a socket, it was in the taillight socket, so we removed the harnesses for the taillights, still blows. This was looked at last night. It is totally puzzling me because markviiisvt4 said that it wasn't doing this a few weeks ago.
