I let my sister in law borrow our beater blazer and when it was returned the seat was forward and gangster leaned back.... not comfortable for me... So I went to hit the switch and nothing. Checked the fuses... nothing is blown.
Is there a separate relay for the power seats? Is there a way to manually crank it? Can I did a power seat base out of a working blazer and slap my seat on it?
What about converting it too a manual seat? Same seat tracks?
Thanks! :-)

Start by having a look underneath the seat and see if she forgot her handgun under there and its jammin something or maybe she knocked a wire connector loose while storing her "piece" under there for the next driveby. Then grab your test light or multimeter and see if you get power to the plug for the seat, its underneath it.
Yes you can use another power seat base from a donor truck under your seat. Yes you can use the base for a manual seat if no power ones are available.

Hi I had the same problem with my 97 blazer. Wife and kids adjust seat and are much shorter than I. Seat was stuck. What happened is some of the wiring right by the switch was getting pinched enough to short out to ground on the metal frame of the seat.
The power for the seat control is sourced through a breaker in the fuse panel. When the wire is pinched and shorted the breaker will trip out then cool down reset and retrip.
If the circuit breaker has not completely died from constant retripping it should be quite warm. You can also check its contacts by ohming them out like a fuse - just to verify it's still ok.
An alternate circumstance is that a harness has pulled loose or a wire has been broken (open) during the seat adjustment.
If a harness is not loose then it is most likely the wires being pinched or broken in the bottom seat pan.
Because my wires were pinched (shorted to ground) and not broken - if I flexed the bottom seat pan or jiggled the entire seat a bit I was able to temporarily remove the pressure where the wires were pinched and lifted the seat up.
I removed the seat - turned it upside down and checked the harness from the connectors to the switches. I found nicks in the insulation and exposed wire. (Look carefully around the areas the wire passes through cut outs or tight corners and surfaces).This was the problem.
I repaired the wiring with heat shrink and tape. Most importantly I rerouted the wires a bit differently to avoid the original tightness. (Just another sh_tty chevy manufacturing problem).
