and won't come back on? It works sometimes and sometimes the light won't even come on. Sometimes it is working and just kicks off and then won't come on again. Any suggestions what to look for?
If your CC is vacuum-actuated, you may have a vac leak that prevents the CC staying on. But it sounds more like you just have a wiring connection that's coming loose, just an intermittent fault. You'll have to spend some time going through the wires.
