hi i got a 2000 jimmy fully loaded whistler edition. my left blinkers blink twice as fast as my right ones. my truck came with towing wiring maybe this is shorting it out? anyone else have the same problem?

also my 4x4 switch should always say 2wd hi when i dont use it, sometimes that button doesent light up i have to press it 2 times to get it lit. whats with that

 

go around and check all the light bulbs, and all the fuses on the blinker issue. i cannot answer your 4x4 light question

 

My 2wd indicator light was going out once and awhile also, I removed the switch and found that the connector on the switch had a bad connection, tighten up the connections and all is good now
