Cruise Control for 86 Firebird
Hello all. I recently got a 1986 V6 Firebird with only 60k miles. Pretty cherry. The previous owner said that the cruise control unit needs a new chip. I called a Pontiac shop and they said there's no such thing. "Could be the servo unit, or the actual cruise control lever, which has circuitry in it." These puppies run about 100 bucks each, but I can't tell which one needs replacing unless I pay out even more money to have them check it. So:
Is there any way to tell which might be at fault, either the servo unit or the lever?
Thanks very much. Love your forum(s).
