GL Dash Switches

[SuspiciousPizza]

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 :]

Run a horn relay that handles the current. Have the switch turn the relay on and off.
