Cruise control issue
Having issues out of my GTA's cruise control function....as in it doesn't function. Lol So far the underhood servo is new, the brake switch is new, and the stalk and underdash module test out good. The cruise will apparently engage once but will not re-engage once the brake is tapped or the connection is broken. I'm not working on the car myself, but has anyone ever experienced this on their car? I'd like to be able to point my mechanic in the right direction
Thanks.
Thanks.

Re: Cruise control issue
If you (the customer) need to point your mechanic in the right direction, I'd go ahead and find a new mechanic hahaha.
Brake switch sticking? Oops, didn't see you said that is new.

Re: Cruise control issue
Just thought I might find others here who have had similar issues that might share some insight, but whatever. I'm not mechanically inclined myself, but we'll get to the bottom of it regardless.

Re: Cruise control issue
Did you replace both brake switches? Not sure which one or if both of them tie into the cruise control.
