I have a 1999 Explorer XLS,when I'm driving the wipers will come on by themselves,the washer pump will not work.And every now and then when I use the turn signal it sticks and there is a bit of smoke that comes out from behind the turn signal assembly where the electrical plugs in.I don't know if these two are related,but someone told me that my GEM might be gone.I don't know much about the GEM.Could someone tell me where the GEM is even located?

Thanks
 






TSB 00-09-06 This is a multi-function switch failure. The multi-function is the turn signal/wiper/headlight switch. It needs to be replaced. Do a search for multifunction switch in this forum, you will find all the needed info.

Hope this helps.

^^^ What he posted. You need a new MFS (multi-f*cked up switch aka turn signal switch). Preferably before the one you have catches your truck on fire. ;)
