I have installed new stereo to Dodge Grand Caravan '00. However it didn't work. Stereo buzzed for two seconds and then became silent. I tried it on my other car (Chrysler Cirrus '99, which has the same harness as Dodge) and its working perfectly. This also proves that I connected wiring harness correctly. Additionally, when I replaced the old stock stereo back to Caravan it worked too. I am puzzled why that new stereo is working on Cirrus but not on Caravan. I just wanted to get rid of that cassette stereo and put CD/MP3 player. Your help is appreciated.
