1988 BMW 735 6 cyl Two Wheel Drive Automatic 189K miles
my classic 735i runs great and is in exc. Condition, well-cared for with no engine problems, but the speedometer/digital odometer and cruise control just failed last week after a 200 mile mountain drive. I did some downshifting into 3 and 2. The tranny is smooth and perfect. I do not abuse the car.
i think it may be a relay switch but there is no diagram on the inside of the fuse box. Do you know which relay is the one to replace, if any? They are expensive and I do not want to just throw new parts at it. I may be able to get an entire fuse box with relays from a salvage yard cheap and start replacing the relays one at a time till something good happens.
all the fuses are fine.
