Ok have some one listen for a clicking sound fro relay when you try to blow horn if there is a sound. Your relay fuse and horn switch is good. Next remove horn use jumper wires one neg, one pos. see if horn blows if it does not buy new horn, If it dose wiring harness has a fault replace it.
Its a Chevy....thats your problem
How to trouble shoot fuel pump on 98 Chevy Venture
no- 1998-2000 Chevy Venture vans only have a relay for the fuel pump and no fuse.
Bad fuel pump, fuel pump relay, blown fuse, or loose connections.
Yes. It should be in the fuse/relay center under the hood.
There are two causes for this. The first thing would be the fuse could be blown, if this isn't the case then the relay switch will need replaced.
check the fuse box on top of the battery.
It is in the fuse box under the hood,spot number 14.
Blown fuse.
Blown fuse? Bad relay? Bad temperature sensor Bad fan motors? Check to see if the fans are getting power if so motor is bad If not check the above
I've got a better question, why is this question in the Chevy venture forum ?
A blown fuse may be the reason a horn is not working in a Chevy van. It could also be caused by a faulty horn relay.
It's behind the glove box under the dash. It's pretty close to your blower motor relay. Just replaced $140.00 from Chevy dealer. It's behind the glove box under the dash. It's pretty close to your blower motor relay. Just replaced $140.00 from Chevy dealer.
