a relay costs $3.. and it wont happen again.
pretty sure A/C is low speed or maybe both, but i know when my fuse was blown to my high speed relay, the a/c would still still turn on my fan.
I have external relays with a fuse for both high and another fuse for low. The stock set up uses 1 fuse for both high and low. If your low speed works but your high speed does not, then I would say you have a melted connection in the BEC under the hood.
cool I'll check that. I didn't know the fan would rn with the relay burnt
There is a relay for high and a relay for low. So it's possible for the low speed to still work while the high speed connection my fail or be intermittent at times depending on the condition of that connection in the BEC.
The 2 speeds are separate, so if the high speed relay burns up and the car kicks on the high speed, you will get no fan at all.

Meh. The relays work the same. 4 post is just a little more dummy proof. That was just a quick Google search anyway.
Defenetly need to use a 40 amp fuse.
On the back side of that connector, there is a 12 gauge green/violet wire. You need to cut and connect to a 40 amp relay. Run 10 gauge from your battery with a 40 amp fuse to your relay. Then cut and use the wire that comes from the computer that normally triggers the factory relay to trigger your new relay, I believe it is a smaller green/violet wire.

Are the trigger wires also in the BEC or are they lumped into the harness somewhere?
