What beats a Sunday Drive?
A Friday drive in sunny 75 degree weather in a rally inspired 355hp One lap VR4 with working CRUISE CONTROL!
Yep, I fixed it and in the end is was simple. At the beginning I didn’t have power to the cruise and the horn didn’t work. A fuse fixed that. The next thing I did was to remove the clutch switch mod that was in the car. That didn’t fix it. Then I swapped the entire cruise control unit to one that I knew worked. That didn’t fix it. Then I swapped a good gauge cluster to be sure the speed sensor was working, and that didn’t fix it. Finally I started to pull out the clutch/brake switches one by one. Each one of them worked so that didn’t fix it. Next I check the switches in place with a continuity meter and the brake switch worked, the lower clutch switch worked but the upper clutch switch did not. I looked at it again and everything worked and I knew when the switch was out of the car it worked so I tried to adjust the switch closer to the pedal. nothing. A bit closer and still nothing. Finally I adjusted it to the point it was loading the clutch pedal and I said..hmmm that’s not right. I looked at the little rubber pad on the lever and it was there but when I got out my mini maglite and depressed the clutch with my hand I could see the pedal moving but the switch plunger was not. !
Stupid Mitsubishi uses a rubber pad where the pedals push the switches and those pads have a nipple on them that pulls through
a hole in the pedal to secure it in place. Anybody guess what size that hole is? Yep, the same size as the switch plungers. The rubber piece had worn down enough to eject the nipple that held it in place so the plunger never closed with the clutch off. So the cruise thought I always had the clutch depressed. I taped a small piece of sheet aluminum to cover the hole and took it for a test drive.
That was it…and now I am happy.

PS. The injectors should be here Monday.
