Does anyone know if there is a duplicate #4 breaker in there somewhere so I could trade one out to see what affect that has?

One other possiblity I hadn't thought of before: Do the power seats work anytime, _until_ you press the defogger (or vice-versa)? Maybe there'* a short in one branch that'* downstream of the control switch, so that it doesn't blow the breaker until you try to use that accessory.

I have this problem too.... this is an old post, but curious to see if anyone has found anything about it.... I am gonna go tear out my passenger side seat.... the pump isn't working and i have the same conditions as this one.
I hit the rear defog button and within a few seconds, i have no power to my seats or my locks. I shut it off, within a few minutes i have power again. Circuit breaker gets HOT.
It sounds like a short... just where and what all is in the circuitry would be nice to know... anyone with a FSM for 92 that wants to lend a hand??

Are you referring to the fuel pump? If so check the ground bus on the driver'* side.
Here'* a Tech info article.

Please do not dig up old threads. If you have a similar problem such as this, start a new thread linking it to the old one for reference.
Thank you.
Thank you.

I don't think this is the one I need.... the FP is fine (seems to be) but the typical door locks/power seats/and rear defogger. I guess I would like to find the wires for the defogger and where the heck they run. THANKS!!
