Alternating Current
as opposed to DC
Direct Current
There are no fuses on the firewall to my knowledge but there is at least two relays, one is the AC compressor clutch relay and the other is the starter relay.
You mentioned relays and wires, but did you check fuses? Fuses or grounds or the wires could still be bad. You have to measure the voltages dropped across them. Good luck.
Fuses and relays are under the dash.. there's a panel you remove on the passenger side (where a glove compartment would typically be on a truck which had one), and the panel is right there.. there'll be a plastic sheet which you remove to expose the fuses and relays, and that has a diagram on it.
All fuses and relays are in the underhood fuse box.All fuses and relays are in the underhood fuse box.
Black plastic box under hood, driver side, above steering column, mounted on fender.
All fuses and relays are under the hood, next to the battery.All fuses and relays are under the hood, next to the battery.
Main fuses and relays are in PD box next to battery. Interior fuses are in a box under dash, left side of steering column.
Check the drivers manual, fuses and relays are listed in there.
The fuses and relays are in the power distribution box.jd
Get a test light and find where you are loosing voltage.
Ac relay is a relay which respond to ac signal only.when there is no supply given to this relays coil,it wont function.it will change its n/o contact to n/c contact if there is a supply given to its coil.this is the simple exlanation for ac relays.
Under the hood on the right hand side. There is a black plastic lid that flips open with fuses and several relays
