Once in awhile the blower will stop working and the cruise control will stop at the same time. When this happens, the cruise control light will come on when the fan switch is either in the off position or on high. Then it will suddenly start working again. What is the problem?

Hello oxl832

Locate the fuse block under instrument panel .
Check fuses:
Low blower fuse 20 A.
Check (power side B1) for power.
Check cruise fuse 10A
Check (power side) B5 for power
Check HVAC fuse 10A
Check (power side B3) for power

Check the .5 BRN wire from the fuse from the fuse block to the splice (S233) for open.
Finally check the splice S 233 for lose/disconnected wire.

The fuses are in series on the power side with the BRN wire.
