For over three weeks my 04 LS radio would not start for apx. 5 min. after I turned it on. I put in two threads here asking what was the problem. Got some great answers from you guys for which I'm grateful. One suggestion was if the trunk was damp. I checked it was not. One day apx. two weeks ago I got in the car and there was no problem. I tested it every way possible. It worked like new and never had the problem. It was getting worse and went back to normal and stayed that way ? Seriously, how could this be ? The only thing that happened at the time I started having the problem I had a mechanic fill my tires up in order to take off the low tire warning signal on the dash. I don't see how taking off the low tire warning signal could have anything to do with the radio. Thank you.
