The cruise control on my '81 Corvette is working, but only if the speed is around 35-40 mph, anything higher it will not engage. Any ideas as to what the problem is? Thanks.
My "guess" is that the control head is clogged with ? and is blocking vacuum passage. You can remove and partially disassemble to clean it out. Since it works properly at some speeds, it's unlikely to have an electrical problem, IMO.
A 1981 Corvette with 5K miles... Did the Golden Gate Bridge also come with that deal?
No, but the original tires, wheels, battery, and most everything else it was delivered with 5K miles ago did. And it just won the NCRS Bowtie Award for untouched originality at the National, with 97%+ in all four categories.......
