CRUISE CONTROL ONLY WORKS IN MORNINGS WHEN COLD

[RAY SUGGS]

I replaced sensor/switch at master cylinder few months ago because it would flash once in the dash but never engage which fixed the cruise control. Then it started working sometimes till it would only work in mornings when truck was cold but it would stop working soon after warming up. Now it will not work at all. Do I need to replace switch in steering wheel ? Thanks

Air bubble between the switch and brake fluid?

Air bubble was the villain when it happened to me.

So, do you simply bleed the line then? any particular wheel? Experiencing same issue, dont know crap about mechanical issues

Remove the switch from the master cylinder. If you don't see an air bubble when you remove the switch then very, very gently lightly tap the brake pedal forcing a slight amount of brake fluid and hopefully an air bubble to escape. Re-install switch.
