So the previous owner of my 98 XJ told me that the power door locks only work when its about -35 degrees (farenheight). Any ideas what could be causing this? i would like to have my keyless entry work when I get my remote start put in. I don't even know where to begin looking though.

 

Anyone? Bueller???

 

It may be that their just getting old and need replacing. Mine open fine at times and at other times the rear door locks stick. Replacement actuators are only $32.00 or so each, so no big deal.
