Re: On again, off again Cruise Control 700 1990

The cruise cut-out switch at your brake (and clutch) pedal is probably right on the hairy edge and needs readjustment (switch has a black/white wire). Also check the brake light switch function and adjustment as it too appears somehow involved (it's the other switch with a green/yellow wire). Other possibilities are dirty fuses, loose wiring and dirty switch contacts, including main cruise switch on steering column.

As to intermittent wiper not happening, you're either looking at a faulty wiper switch, a faulty wiper relay or the contacts inside the wiper motor are worn. Because you say the washer pump isn't working with intermittent wipe then it's most likely the wiper switch as the relay isn't really involved in the washer function. But in case I'm wrong (wouldn't be the first time), get a wiring diagram and isolate the problem with a meter. Relay should be back row, second from right.
