2 things wrong with this post.
1. a good or bad connection will not be an issue tied in with your windows going up and down or turning on your blinkers.2. tape should not be used when installing a car stereo.
It has to be an issue with your 12v constant wire or 12v ignition. Sounds like it has been re-wired and you are using a 12v wire that is also being used to power your windows, and blinkers, and when using the radio with one of these it doesnt have enough amps to power both. run new 12v constant from your ignition harness and 12v ignition from your ignition harness. this is very easily acessed under your steering column. good luck.
