93 fleetwood - the cruise control works when it wants to. may work everyday for a month, then not work for a month, then start back again. i changed out the “thing” under the hood. got the exact same results, this tells me the “thing” is working, or i have 2 bad ones. any other ideas ---

You might want to check your brake light switch. When your cruise isn’t working, check to see if either your brake lights are stuck on or not working at all. ---

I vote with **Triedaq** on the brake light switch. It’s the most common component to go bad in a cruise control system. I call it the “weak link.” ---

Might want to check the 3rd brake light bulb. A burned out bulb disabled the cruise control on my 93 Caprice.
