Truck Parts Review InvitationI have changed the switch under the clutch pedal. when the truck is parked the cruse control is working when I release the yellow button (release the parking brake) and is doesn’t disengage it. it seems that the problem lays somewhere there, but I cant find out what is wrong.

Response from Vicki:

Hello. Thanks for asking a question about this truck part.

We are not qualified to render mechanical advice about how to fix this problem. Perhaps one of the readers of our site will be able to provide guidance in the comments. Or perhaps you need to take your truck to a truck mechanic who can figure this out.

I know that years ago, one of the trucking companies for which Mike and I drove had their tractors set to kick off the truck cruise control whenever the headlights were on.

If you are mechanically inclined, check to see if there might be something “else” — perhaps a sensor, relay, wiring scheme or engine setting — that is preventing the cruise from engaging and disengaging at the right time.

Please be very careful to make sure that you don’t wire up your rig in such a way that it can become a “runaway” truck that won’t stop.

When you get this issue resolved, would you please return to this page and share what the issue was and how you fixed it? Thanks in advance.

Mike and I wish you safe travels and lots of money saving opportunities on the road.

Best regards,
Vicki Simons
