Check behind the battery in the fender. I saw a website saying that it is a 30A fuse in that location. I'm looking for the same on my 2001 S10 and I can see some electrical relays or something but still need to remove the battery to get a better look to find the fuse. If you find it elsewhere please let me know.
The 2002 Chevrolet Trailblazer air pump can be found on the firewall in the engine compartment. The air pump will be on the passenger side of the firewall.
The fuse is next to battery; under the horn, in the opening in the fender well.
the location of the air pump on 2005 Chevrolet trail blazer
in the fuse box
NO.
On the passenger side under the hood there is two fuse boxes. the smaller one will have the two fuses for the air pump. The top 50 amp fuse is for the air pump the bottom one is the Air relay.
The 2002 Chevrolet PCV valve is located on the outside of the air intake housing. The valve will be on the back of the housing.
If the secondary air injection failure code comes up you shold propably check the air pump fuse. I think it is call the air pump. The fuse is rather big. Sometimes water gets into the air pump and causes it to trip out. the fuse is loacated on the front pasengerside close to the bumper. Some people say that you will know that the fuse is out on the air pump because the hood light goes out. That's not really true in all cases.
in the front under radiator
you have either a bad relay, bad fuse or short to ground
Fuel pump relay fuse is under the hood drivers side next to air filter.
Something is wrong with the rear air shocks- either it is the shocks them selves or most of the time the air pump... But first check your fuse to the air pump. see owners manual for fuse location.
