multi funtion switch stops working had it replaced once b4

Had the multi-function switch replace when truck was 5 years old under an extended warranty I purchased. The Warranty has run out. The Switch controls the wipers, high beams, turn signals, 4 ways. and what happens is the function will not work or works the wrong function you want, ex: turn left signal on right turn signal comes on or try high beams wipers come on. Get very annoying and is a safety problem. the replacement switch has lasted 4 years now have to replace it again
