I have a 2001 caravan. When I'm driving along and engage the cruise control, the light comes on and the cruise works for about 30 seconds. After that, the light goes off and the cruise will not work. I cannot re-engage the cruise control again unless I turn the key off and restart the engine.
The engine check light does not come on. There are no error codes when we check the main computer.
I just changed the transmission computer and had it flashed. The problem was that the car was in limp mode and the computer was all messed up. I did not have the cruise problem prior to the change in the computer. The speedometer is working.
Does the transmission computer have any effect on the cruise? Could the new computer be defective or the flashing was done incorrectly? I never had a problems with the cruise until I replaced the transmission computer. The speedometer is working so that's not the problem.
