2007 dodge caravan stock radio volume issue
 

Hey everyone, iv been having problems with my radio, I'm not getting any volume the knob only moves to 1 and 0, this is the second stock radio, my first one had the same problem it would work and suddenly shut off ( the weird thing is it seemed to only happen on really hot days) it would work again after I turn the van off and then back on. Eventually it just stopped working completely, so I bought another one that worked fine for 3 weeks and then stopped completely. I have no clue I feel like it over heated but I'm unsure.
