Fuse keeps blowing regardless of its value!

[Iyse]

My right electric seats weren't working on my '97 Box, so I check fuse box and sure enough, fuse has blown, so I replace it with a 30A (which is what is specified), move seat a little up and fuse blew. So put another in and as soon as I tapped the switch it blew. Happened 3 more times, then tried 20A, 15A, 10A, all blew. There was a 25A in there before, but obviously blew because I'm having this problem.

What could be the matter?

Worn wire rubbing on the metal frame?

Shorted motor?

I had the same problem and posted the same question in the 996 forum.

For now it seems fine, I had looked under the seat and fumbled with the wires,

so I guess I must have accidentally moved the chafed wire off contact with some metal part under the seat.

I blew about 4 fuses before it finally worked, but something is not right.

So, I'm waiting till it's cooler in the garage to take the seat off and look for the fault.

Please keep me informed if you find anything. ;)

You need to start from the motor then work your way back toward the switch.

1. Pull the connecter off at the motor, then try operating the switch again. If fuse no longer blows, problem is probably in the motor or maybe the drive mechanism to the seat.

2. Re-attach connection and verify if it still blows fuse. This will discount whether the wires are chafed somewhere underneath the seat. If fuse doesn't blow here, look for worn insulation on wires.

3. Remove motor from seat, connect wores and see if motor will blow fuse without being connected to the seat mechanism. If motor runs by itself, look for binding in the seat mechanism.

Also, your post makes it look like you tried going down in amperage ratings on fuses to try and solve you problem. That doesn't work. Higher numbers means more current = more power to motor. Whatever you do, do not use a fuse with a higher numeric value than the manual recommends!

I was looking under the seats and I can't find the plug to the motor. Is is the white plug with the green and black leads going in??

Thanks.

I'm in the middle of the same problem.....Interested to know what others have done.
