What suggestions do you have for finding a short to the back up sensor in my 2007 Cabrio. Whenever the road is wet in the winter along with the salt from the road crew the 5 volt fuse blows. I don't know which sensor it might be or what to do about checking where a break might be.

When the roads are dry the sensors work fine, and even in the summer, but in the winter they blow the fuse. Any suggestions.

This fuse often blows when the ps fan is stuck/bad...
Same circurt....
check it out imo, might be simple to fix.

 

My 07 had the same thing-it was the PS fan.

 

ditto on my 05.
