So I thought the winter season was over and left my front window open about a half an inch since I have rainguards and just wanted the car to air out a bit in the nicer weather. Freak snowstorm saw winds blowing sideways, woke up to my drivers side window controls covered, and snow blown across my dash right into the center vent above my radio. Cleared out as much of the snow as I could but it was all up in the vent. No problems with my windows or locks, but I think the snow that went in the center vent melted into the radio causing me issues. Immediately after starting the vehicle the radio did not work or light up, about an hour later radio lit up but I could not hear any music coming out of the speakers, if I turned the volume all the way up I could hear some really low thumps coming from the crappy factory sub at the rear passangers side. Left the radio turned off and tried it a couple days later and everything was fine, radio played great for a week. Then we had another cold spell and the radio is back to just the very low thump when volume is turned up to max. Now that we're seeing warmer weather I think I'll rip the dash apart without as much risk of breaking any clips so that I can see if theres any visible damage. Anyone have any suggestions of things I should look for or any way to trouble shoot this problem? I was thinking of checking for corrosion in wiring harness and potentially opening up the radio and wiping the innards with some IPA. Anyone? Bueller...?
