If the switch is anything like the window switches in a 5000 or 200, you might not need to take it apart. I found that a generous spray of WD40 into the switches interior may work. Remove the switch from the door handle and carefully remove it from it's plastic case, then spray away! Good luck! Scott Spangenberg 89 200T, 180k mi 85 5ks, gone 79 5ks, gone
