It's not a matter of IF your window regulator fails...
It's WHEN are they going to fail...

Mine quit when it was winter time and I had to drive to DCP in 35 degree temps... Not a fun cruise...

Don't know if this is a temporary price drop or permanent...

VPA has them for $295 ea. Have not checked if Parts Rack has them too...

either way at these prices go buy them!
