theres no such thing
In the fuse & relay center under the hood.
That other relay should be the AC compressor relay.
The relay on the passenger side firewall is the ac compressor relay.
AC compressor clutch relay, starter relay, high speed blower motor relay,
1995 to 1998 S10 fuel pump relay is located in the glove compartment behind the door marked "relays". It is the first relay on the left.
The drl relay is located in the back of the glove compartment.
The AC compressor relay is located under the hood, on the firewall, passenger side.
where are the timing gear marks on a 1997 chev s10 2.2 located
Under the hood on the drivers side firewall, close to the drivers side fender.
fuel pump relay
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.
The fuel pump relay for the 1998 S10 should be found in the relay/fuse center under the hood. The fuel pump relay for the 1997 S10 would be found in the back of the glove box, first one on the left (closest to the driver).
