Reader Question: I have a 1993 Dodge Grand Caravan 3.3L with 245,000+ miles on it and well maintained. My (replacement) radiator fan burned up/shorted out big time. Magnets came loose and spun with the armature.
I overheated the engine and blew my plastic radiator! I replaced the radiator/replaced the fan completely. Started van, warmed it up but no fan. I clicked the AC on to start the fan with the compressor, eh…nothing.
I checked all the relays (5) on fender by the battery. I switched them around since I do not know if one is for the fan and AC still no results. Two of them killed the engine upon removal…LOL!
Is there a fuse center that I do not know about?
Should I reset the brain? I cannot find a 40A fuse for the fan anywhere! I am trying to gotta keep er going.
By the way, the AC is completely new, even the hoses work(ed) great!
Now, I know the burnt fan motor has blown something. However, I do not know what it is.
You should have a gray wire with an orange fusible link behind the battery area. You can usually feel these fuse links with your hand to tell if they have burnt up, the fuse link orange part will feel rubbery and softer than the rest of the wire. Start with that first, since the fan motor burnt up the fuse link probably did as well.
It also looks like there are 3 relays for the cooling fan, 1 Low speed relay and 2 high-speed relays and a radiator fan switch that is located in the high-pressure hose for the AC. It looks like two of these relays are on the right fender, and the other one is on the left fender.
You might want to check the fuse link first and follow the circuit around from there.
