Hey guys, doing some work on a friend's e21. He wants to do an electric fan install. I'm trying to do it the cleanest way and use the bmw switch 6131136427282 to activate the electric fan. However, he wants to keep his A/C condensor and aux fan and there is only one sensor boss on the radiator.
What problems would arise wiring it so both fans are activated by one switch and as such both turn on at once? Do we even need both fans?
Situation A: fans kick on when temps rise sitting at a stop light
Scenario B: fans kick on when A/C is turned on
We have a 16" Spal fan acting as a puller in place of the clutch fan. Could I eliminate use of the aux fan altogether so the Spal could both cool the radiator and in theory the condensor? I say in theory because his A/C doesn't work but he wants to keep it all there so we're trying to plan ahead.
Thanks all
