So basically I am having some problems with my climate control and radio and I want to know how to fix it. Every now and then, for no apparent reason my front defroster will turn on full blast and the highest temperature and I have no control over it. The head unit locks up and I cannot do anything. The radio will also lock and stay on whatever station I was on and at the same volume so I am guessing the problem is with the whole unit. Any help is appreciated thanks!!
