Reply to "rewiring the fan relays?"

Johnek, know that I am also electron-challenged. There's one simple li'l mod to stock OR aftermarket relays that anyone can do. MOUNT THE RELAYS in the 'inconvenient' wiring-down position instead of the factory wiring-up position!
The reason is simple- if you ever hit a big puddle or drive in actual rain or snow, thrown-up water will pool on top around the crimped edges of the relays when they face up. Relays are NOT water-proof, only water-resistant. The pooled water will work its way inside the relay, rusting and shorting stuff. I've disassembled quite a few stock fan relays and ALL were rusty inside. Note the relays can be opened and guts can be cleaned, restoring some to operating condition.
Do your work as necessary, then rotate the relays on their stock mount bolts so the connections face downward. Just a li'l maintenence/longevity tip that costs nothing but a minute's effort.
