Fellas, this morning I'm warming up my truck with the defroster on. everytime the AC pump cycles on and off my radio cuts off and on. This ever happen to anyone before. If so any ideas what I should check. Thank's.

It sounds like the intake manifold heater cycling is causing that. That's a normal thing when the weather gets colder. Your batteries may be getting weak so the cycling has more affect on things than it should.



If you haven't been maintaining your "maintenance free"(???) batteries they may be low on water.
