I have a 99 sr5 v6 4runner, all at once my power window master controller started to malfunction. the problem is, I have no power to any four windows from the mcu, at the same time the front passenger window control stopped working. the two rear window buttons work as normal, also the power door loocks, power mirror control and window lock button are all still working. I have checked the fuse and also have disassembled the unit cleaned and dried inside for two days. any suggestions are much appreciated.

 

anybody?
