93 New Yorker Serpentine belt problem

In fact, they do. Chrysler engineers deemed the original idle pulley 0.08 inches out of line. When driving through deep snow (i'm in edmonton canada, and alleys have deep snow) it just comes off yep. Everytime and man is it annoying. I found a post somewhere about this problem, except that guy was having the issue due to deep puddles in florida.
I am aware that the idle pulley may not be the issue though, I have taken a look for the belt being out of alignment. With the naked eye it looks fine. Is there anything I can do with this tensioner. Or simply replace it.

Thanks for your response and valuable information, it is appreciated, im by no means a mechanic, but the simple stuff I can do. I even changed a tranny out in my car when iw as a teenager, 4 speed to 5 speed alone. Little car. Lol have you ever heard of random electrical problems in these cars? I think all my problems may be coming from the air suspension compressor that no longer functions :( just after some digging and reading thats my impression, its 8am im going out in the snow to work on the car soon. Should be fun! Im a computer guy btw!

Not really but im sure going to try. Thats just from information I found on the net. The electrical has been ongoing for a year. Power door locks having what I call 'seizures' from time to time.(How embarassing) been through 3 batteries. I know I have a short I just dont know where and havnt an idea where to start looking. What I really need is a mechanic that has a computer that needs fixing! Lol
