aux fan
 

Does any one know the cfm specs of a stock 420sel condenser fan? Or. does anyone know how to rig high fan to come on with the a/c on? I think my stock fan's low speed is too inadequate for san antonio stop and go traffic. I was once able to make the high fan come on all the time by disconnecting one of the green wires on a sensor in front of the engine, but it seems after a while the fan would resume normal operation even with the wires disconnected. Thanks in avance for any replies.

Answer:
 

Jumper the A/C temperature switch wires at the reciever dryer = AUX fan will run any time the ignition is on. :)



Have a great day.

This is true, but I need high fan.

Jumper the Aux Fan temperature switch wires at the thermostat housing = AUX fan will run on high any time the ignition is on. It is the 3 prong switch jump the two that are side by side not the single one

So take a piece of wire and jump between the connectons on the wire itself?

The pins are on the switch and the female connectors are in the wiring harness. Take a small piece of wire and short out the two pins that sit side by side. Then put the plug on the wiring harness back on the switch.

Do not put the jumper wire into the female ends and reconnect the plug to the switch. Doing this will expand the diameter of the holes and will cause a loose connection after you remove the jumper wire at a later time.

Hope This Helps!

Ahh. Thank you
