![]() ![]() The relay gets thrown by power from the gauge fuse, (enabled by ignition), then to the fan speed control switch. The Fan 1 and Fan 2 relays underr the hood are for the cooling fan, the one between the engine and the radiator, so they won't affect the interior blowerPower comes from underhood 100A ALT fuse (if that was blown, the heater would be the least of your worries) then to the 40A Heater fuse under the dash, and then through a Heater relay in a junction block up above the glove box. at the other settings the radiator fan is not turning on.** checked the 40amp fuse in the fuse box under the steering wheel and the 10amp for a/c and all is good there.Could it be the relay in the fuse box under the hood? The FAN no.1 relay or FAN no.2? I removed them but I dunno how to tell if they are still good Thanks!Dan ![]() when I turned the dial at the defrost setting it turns on the radiator fan but no air is coming in the car. I didn't check the fuse because I think it's says it's the same as the cruise control & it's working.Any help would be appreciate coz I dont feel like going to the garage especialy when it's just cost me 600$ on my mini-van ** Update. A/C turns on, defrost, hazard, cruise control. Good Day,It's raining today & I wanted to start my fan to remove the fog off my windows when I noticed it's not working anymore & I was driving!!It's not working at any speed & it does nothing when I tried to star it.
