Had a 1643 thrown in the rain the other day....TCM fault, thanks to you all I was able to find out how to fix, I pulled the scuttle cover and wipers, replaced the cab filter (old one may be the oe from the factory) as I can no longer slide under the dash and figured it was a water leak opened the windows and hatch to dry out the inside...Just checked and after removing code took it for a short run...all is good...thanks for the help

 

Info we got when these cars were in NEW CAR WARRANTY.

 

Thank you for the info...I think the water proof seal idea maybe the way I will go...I can not crawl under the dash anymore so will have the TCM pulled by my garage.guys and see if that helps...otherwise it's never driven in the rain type...
