SuspiciousPizza Posted Friday at 12:35 AM Share Posted Friday at 12:35 AM One of the previous owners before me installed an aftermarket switch for the A/C condenser fan (now used as an auxiliary electric radiator fan). The switch did not fit well and it would fall into the dash if I pressed it incorrectly. It also felt of very suspect quality. So my idea was to use a spare rear wiper switch and install it in a switch slot that was otherwise filled with a plastic blank. However, I worry about the amperage rating of the rear wiper switch. The fan pulls 10A max but the rear wiper motor and washer only pull ≈5.4A collectively. Would it be worth it to give it a go? I just don't want to burn out the switch and damage a good OEM part. Thanks :] Link to comment Share on other sites More sharing options...
el_freddo Posted Friday at 10:05 AM Share Posted Friday at 10:05 AM Run a horn relay that handles the current. Have the switch turn the relay on and off. Cheers Bennie Link to comment Share on other sites More sharing options...
SuspiciousPizza Posted Saturday at 12:11 AM Author Share Posted Saturday at 12:11 AM (edited) So as it turns out the previous owner had the same idea as you, Bennie. He wired the cheap switch into the A/C fan relay in the engine bay. Doh! Well that's good news, less wiring for me to do. Does anyone know if these rear wiper switches are illuminated? If so is it illuminated all the time? Thanks :] Edited Saturday at 12:12 AM by SuspiciousPizza Link to comment Share on other sites More sharing options...
