Blinker click problem

Hey, I have a 99 Envoy that has developed an annoying problem recently. Ya'll know how there is that clicking noise whenever the blinker is turned on? Well, my envoy now does it all the time, whether the blinker is on or not. The only time it stops is when the brake is applied. I have a feeling that some wire is loose somewhere, but im not totally sure. Have any of you had this problem, or would any of you know what to do to take care of it?
Thanks in advance for any help!

Re: Blinker click problem

One possibility would be a loose ground. I would check underneath the rear of the vehicle. There should be a bundle of wires leading to the lights and a ground coming off of them. Should run along one of the frame rails.
My 89 Sierra blinkers started acting exactly like that when I took the ground off to put on a hidden hitch and forgot to reattach it.

Re: Blinker click problem

1st, im not familiar with the 99 envoy but the clicking you hear (if it is the turn signal) is from the relay to turn the lights on/off. It is usually found somewhere under the drivers dash, most likely on the firewall. Get down there and see if you can pinpoint where the clicking is coming from. If it is a relay, pull it out and clean the contacts on the relay and where it mounts. Radio Shack sells a electrical contact cleaner spray you could use.

Hope this helps.
