is there in line fuses for cruise control
No. it is protected by a fuse in the fusebox, could also have the horn on the same circuit.
The deactivator on brake peddle works,also the wipers speed control stopped working. The wipers only work on high speed. This all happened in a two time frame?
Also the relay&fuses are good
Then you need to check the power to the cruse control servo assembly, if you have power and the unit is grounded, then you will have to check the ohms for the switches at the control module for the cruise control, the shop manual should have the resistance readings for each switch function.
Thank you so much for your expertise in this matter
