Are there any chemicals that are reccomended? I cant easily pull the two parts apart, and theyre not soldered together. It is actually the two wires for the aux fan that trigger the aux fan. I have a new fan, and it works when I jumper the wires, but sometimes even when jumpered it doesnt start, as the connections, despite the rubber boots, are corroded.
Thanks for the reply, and TIA for any others.
