thank you for that info but i had already read that one and a few others like it when i did a search and went thru the check list that was posted, and all my stuff seems good ,no water leaks,the battery int he car is good the battery's in key fabs good.......i have gone thru all the stuff that i could find when i did the search ....the only thing is maybe the unit itself but will that also make the lights go on and off ?
