Ever since a car wash my cruise control set light has been blinking and cruise control can not be set. It worked for a half hour trip today but when I turned it on to come back it was blinking the whole way home.

Do you clean your dash/steering wheel with ArmorAll or something similar? That stuff will ooze into the switches and foul em up. You can take everything apart and clean the contacts really well and that might take care of it.

almost sounds like a loose connection somewhere along the lines.

I agree but where. The car wash could have been coincidence I didn't drive her for a week while I was on vacation then the first drive I happened to get a car wash and happened to notice the light after honestly could have been blinking before the wash impossible to be sure . One thing though I did just have my timing belt water pump cam seals and thermometer replaced right before my trip.

Auto or stick?

If it's a stick, then when driving, see if you can pull up the clutch pedal with your foot and see if the cruise will work. If not, then try pulling up on the brake pedal and do the same thing.

Do the same with an auto trans, but just for your brake pedal. If this makes your cruise work, then you have a bad or misadjusted clutch/brake switch.

Otherwise, unplug the cruise module (located on the passenger's side inner fender, near the firewall) and then blow the connector out, plug it back in and see if it works after that.

I'll do That when I get back from the lake on the first thanks for a quality answer

Thanks for the quick detailed responses and answers ill try them on Tuesday when I get home keep the ideas coming so I'm armed with a lot of troubleshooting ideas but I do appreciate the responses

But not the actuator, which may have got moisture in it from the car wash, under the hood (has the cable running from it to the throttle).

I guess I should have called it the actuator, not the module.

You're right (as always). When I read it, I read as the computer, not the actuator.

Cyclemut is referring to the actuator, under the hood (has a throttle cable attached). My pic is of the computer, which is under the steering wheel. check the connections at the actuator.

See labeled pic; between the wiper motor and power steering tank on the left of the pic next to the fender is the cruise actuator.

Looking tight and being tight are different. You'll want to pull the plug, blow any potential moisture out of the plug and the socket, then reconnect it.

I've got the same thing now it's been a few weeks. When it doesn't blink, and if it works and I'm using the cruise control, turning the right turn signal can disable the cruise, and once in a while, the left turn signal will do it. It seems to happen most often on rainy days, but it's been cold to very cold with snow, but I have a hard time associating it with rain and this, the problem is outside the cabin, when I want to say the issue is in the wheel or column controls because of the signal lights affecting the cruise function.

Some say it's the cancel switch on the brake pedal, but I don't see that either, but worth a look. But I'm mostly wondering if anyone with my symptomes have isolated the issue.

Quick snippet from the FSM regarding the lights for the cruise system....

Cruise_zps5c2536a8.jpg


They get their power from the fuse panel (fuse 11), then the ground is supplied by the cruise computer to light up the LED in the dash.

So if the light is intermittent, it makes it sound like the computer is at fault. Unless you have a genuine short that is causing the LED to light up in a way that is COMPLETELY un-related to the cruise system.

I haven't had a chance to check it out. I spent more time in the field than not after coming back from my Xmas vacations, but I have Monday off and planned to use the mother-in-laws garage (since it's -20*C out) and I have the day off from being in the field, but this past Friday just popped out 2 new problems, or probably/hopefully, symptoms to this problem:

Only with the headlights/running lights on:
- Left signal light stays on after use, mind you it's a bit dimmer so you can see it brighten with the signal light when in use after, but it can only be reset by turning off the headlights and back on, and sometimes you need to signal to the right.
- Brake lights are all.

I"ll check the cruise circuit, but I'm also going to maybe look at the tow harness after, just to see if that doesn't fix anything.

So in the end, the problem was related to a badly corroded trailer harness. Sadly I had just installed a 7-pin this summer so everything was fine and dandy and it corroded where the two 4-pin connectors connected. Corroded so bad that one of the pins broke off into the other one. It was probably caused by all the salt and brine that was shot up by the rear wheels, but to do this after half a winter surprised me, and I wouldn't of guessed that it would of affected the cruise control like it did. I'm just glad it was an easy find and an easy fix. Well, it's patched up for now, but I'll need it in March, but resoldering a new connector is easy-peasy, i'll do that later.
