1990 CADILLAC FLEETWOOD CRUISE CONTROL NOT WORKING
1990 CADILLAC FLEETWOOD CRUISE CONTROL NOT WORKING.
Replaced the ECM with an AC Delco module.
Did not fix the problem.
Codes start and then stop when it comes to the control.
Cruise went out last year.
Now it will not work at all.............
Dear JERRYMCGOVERN-- The cruise control module is just one component of the cruise control system on your 1990 Cadillac Fleetwood. Since that is new, you will logically continue and check the speed sensors (usually the speedometer will not work), the actuator, the throttle linkage or the sensors on the brake pedal. For a pretty decent description of most systems, try the following site-- http://autorepair.about.com/cs/generalinfo/a/aa100302a.htm. Good luck from Bovan.
Thank you for the info. I will check all the other sensors this week. One checklist is 55 steps long about the speed control. Jerry
3rd brake light bulbs must be working.
