My a/c clutch cycles too much, why?

If it's a domestic vehicle, the Clutch Cycle Switch may be bad. Simply remove the old one, apply PAG oil to the threads of the new switch, and install. Wear safety googles.

When I am pulling trailer the a/c will sometimes warm up

It could be a bad Clutch Cycle Switch or there could be a problem with the Blend Door Actuator. It's common for the A/C system to ice up, if there's a problem with the clutch cycle switch--check it out.

Thanks will look into that
