Power seat problem
Hi Everyone,
I have a 78 pace car with power drivers seat that's not working I checked at the switch and I have no power and I have checked both sides of every fuse and they are all good
Does anyone know if there is a relay or something else that would control the power?

A power seat was not available in 78, 81 was the first year it was offered. If your Pace Car has a power seat, someone has installed a power seat from an 81 or 82.
That I know of, the power seat, didn't have a relay. There is a harness that comes off of the switch, with two connectors on it, one that goes to the seat motor, and a second that plugs into the main body harness. Both the switches and motors on those seats, are known to go bad, but since you say that you have no power to the seat, and 78's were never offered with a power seat, are you sure it even has power going to it?

Are you saying that the drivers seat is from an 81 or later car or do you think they added it to the existing seat and if so were the later seats the same color and style?g
There is a harness coming off of the power seat switch and reaching under the seat there seem to be wires connecting to it I tried lifting the rug from the side to investigate but the rug is still kind of glued or held in place so I guess I'm going to have to remove the seat to track it down

It takes floor pan modification but the '81+ power seat will fit in earlier C3s. Excepting the seat base the rest the same so pace car seats could easily be bolted onto the power seat base.
Power seats only need a +12V power source and ground. I suggest tracing the wires leading from the seat. Power seat motors are fairly power hungry and designed for intermittent use. In every factory installation I've seen their circuit is protected by a self-resetting circuit breaker (like headlamps, wipers, power windows) but who knows what was done with a non-factory install. There may be an inline fuse. It's also anyone's guess where/how power was obtained.
