Help please: My turn signals are not working. I checked fuses there good. Do i take off part of dash board to replace hazard switch? And now my speed dnomitor is way off and door locks lock when they want to ? Any suggestions?

 

could be either the hazzard switch or possibly the multifuntion switch, if u do the multifunction switch you dont need to take off the dash, also with all of these weird things going on you should also consider the BCM
