We are having trouble with the power seat on our Blazer. The seat has no power going to it and therefore wont move. We have run an external 12V wire to the seat to power it and it works fine that way. However we cannot figure out where the wire that plugs into the seat gets power from. Where does the wire run from and to the seat? Is there a fuse or circuit breaker somewhere? We need to get the power back to the seat somehow so we can get rid of the auxiliary wire that we ran.
Thanks

Hi Robert,
The seat moves weather the ignition is on or off, I believe, so it is connected directly to the battery lead, and probably has a fusable link, or a pretty good sized fuse.
The operators manual has a chart telling what fuses protect what accessories.

Van,
We have tried looking for the fuse and also looked in the manual. We have taken it to a local garage and they could not locate the wire or help us. That's why I thought I would look for an answer from one of the experts on line here. Can you give me some further assistance on this?

Hi Robert,
According to the book I have, there is a circuit breaker on the fuse block. It is 20 amp, hot all the time, and operates the seat, and the door locks. It is called the power accessory circuit breaker, and I would assume it is supposed to be self resetting.
The circuit # is 540, and it runs through a orange wire.
The circuit breaker will look like an oblong square metal box, about an inch long, and 1/4 inch square.
Good luck,
Van
Van,
If the same fuse powers the seat and power locks, any suggestions why the power locks work fine and the seat don't. The wire going to the seat does not have any power to it. All the power accessories (windows, locks etc) work fine. Do you know where the wire runs from and to so we can maybe trace it and see if it could be broke somewhere. The seat just quit working one day, which we later determined that it was due to no power. Any further suggestions or ideas?
Answer -
Only suggestion I have about that is, the breaker is fine, and there is a connection problem in that wire.
My guess would be the connector that goes through the firewall.

Ok thanks. I guess you don't know where the path of the wire runs from and to. I am just inquiring where I could check it at to the closest point from the fuse block and then along the way to the back of the seat where the connection is.
Thanks
Robert
AnswerHi Robert,
GM generally doesn't run a wire under the carpet, nor under the body.
When you open the drivers door, and look where the carpet ends beside the door, there is a trim piece that holds the edge of the carpet down. If you remove thar piece, there is a little tunnel under it where they run wires. I would expect yours to be there, although there is also one on the passengers side.
But the drivers side is where I think it would be.
If you have bucket seats and a console, it could be under the console, but I expect the tunnel.
