Cruse controll

[rrhayden]

Does anyone know the proper electrical checks for the cruse controll. Mine quit ( blew the fuse ) and now does not work. I replaced the fuse, and it does not bolw, however the system does not work. I am thinking it is an electrical issue in the switch or wiring.

Thanks

The weak link in the cruise control is the dis-engage switch on the brake pedal. It is made of plastic or nylon. The lock nut backs off so that the brake pedal does not engage the switch.

There are 2 vac lines on the cruise servo. One goes to the vac canister in front of the left front wheel. The other one goes into the firewall behind the battery. Pull this hose off of the servo and suck on it, (yes I am sucking again for all of you who remember the brake booster), if this line does not hold a vacuum then your problem is the switch on the brake peddle.

If you are as big as me, get a kid to help you. Pull the hush panel, and tighten up the lock nut on the switch.

Now if you wrap a nylon tie wrap around the switch and its mounting bracket and snug it down good and tight you will never have to make this repair again.

Thanks,

I feel better now to know I am not the only one that would suck on the line to see if it was open. Must be a sign of a true genious.

The switch does hold vacuum thus I think it must be electrical. I thought it might be the servo, so I traded on from another car and it still did not work.

If it is electrical Vig is the man you need. He is probably over on the C2 forum working on his ¨new¨ car.

Check all of the grounds. Most of a Vette´s electrical problems are ground related.

The blown fuse could have been caused by one of the solenoids burning its self up. After the thing burnt up there would be no more current draw which would be in keeping your symptoms.

My cruise kept blowing fuses. A wire in the steering column had been worn and shorted out the cruise control. I didn't have the time, patience, or expertise to pull the steering wheel, but a new found mech did a great job finding it, replacing the wire, and wrapping the wire harness in the column for $250. That may seem like alot, but when it comes to electrical, I thought it was worth it. Good luck finding the problem.
