Below -5C, doors freeze on my Mazda 2003 MPV. Even the key hole is plugged and have to wriggle the key in and rock it back and forth to open the door latch. The back doors stay frozen and do not thaw until after three or four hours of driving. My kids use the front door to go through.
This seems to be a common problem for MPV. Any suggestions on improving this situation?
Thanks, Sri.
