Canadian update for 180's chart
I bought a battery from Napa #48-6 was 202.33 list (I got it for less as the company I worked for has an account) It is an exact fit - same handles same size, same holes for positive terminal cover. Only difference is it is black. It came with a black vent plug and a 90 degree vent elbow - I used my originals so I could keep the little white reservoir so no drips. Has a 24/72 warranty and 700CCA / 875 CA
I called Mercedes locally and they wanted $234.70 Cdn list and Chrysler was 177.00 Cdn list. I tried my local Canadian Tire but did not have stock.

Now for my problem. A week ago last friday I left the lights on and had to have my car jumped. I started the car numerous times with the old battery after the jumpstart but on the last try the spoiler light was blinking - I read that is a battery issue so I put in the new battery Sunday. Since then the spoiler light kept flashing and spoiler would not go up at 100K/65 miles per hour (numerous tries). This monday morning I got in and it was not flashing so I pressed the button and the spoiler came up -then began flashing again and still flashes. The spoiler will not come down now. I just tried the roof and it also will not come down but the windows do come down when I unlatch the roof then I just get beeps. I have read every thread I could find on blinking lights, spoilers, roof and batteries and no ideas. My ESP/BAS lights are not on and I did try the steering wheel reset just in case. The divider is in place. I tried removing the battery cables for an hour to see if it would reset. I have checked every fuse (all three panels) and have no idea where to go next. If it was a roof problem the spoiler shouldnt be blinking if it is a spoiler problem why the roof issue? Did I blow my RCM?
