OK, I moved my sat radio ant to a new hidden spot under the cowl vent. It works good, plenty of signal everywhere I've traveled. Then this morning I was sitting in my truck cooling off in the AC with the sounds on and when I turned up the AC fan to high, I lost Sirius reception. I turned the fan down one click and the siginal came back!! So with the AC on high-no signal, 3/4 up-full signal. WTF could be going on? Bad ground on the blower motor?
