hey everyone, im still around, my 2.5 in terms of my last rebuild, the engine runs perfectly fine, with exception of a new problem that has arose....

a couple days ago, my radiator blew apart, the top exploded and it blew the radiator fan into the engine...

i located a brand new radiator, put everything back together, and noticed my fan doesnt want to kick on, thinking it may be the relay, i swapped out with the AC relay and No Go..... So i find another fan with just wire ends from like a honda..... plug it in place, even flip the wires around, and Nothing happens....


all i am seeing is the relay and thats about it.... what switches the fan on and off...

 

fan is on/off by the PCM via relay. Did you check the fan's fuse? Possible it popped from a liquid or contact short.

 

On our 2.5 Dakotas two things is my understanding the water temp sensor and the A/C by the PCM.

Check the water temp sensor or just buy a new one and see if that is the Fix.

If not you have another problem is the fan ok?

I forget what year is your Dak?

 

I put another fan in place but nothing happens

my dakota is a 98

water temp sensor is new, should be good, but i can swap it in case

the relay isnt the problem and Either i have 2 bad fans OR something else is bad

 

Look on rockauto for a replacement fan I found out by accident that a 97 and older 2.5 Dak has a replacement fan for $30 but it has a different power plug it looks like it should work.

 

so the fans both run when i wire them directly to the battery, so Something else is the problem, i may as well just reinstall my fan and go down the line, the temp sensor is next just because it has a warranty, quick swap in a AZ lot

 

AZ you mean Arizona?

Your in AZ?

 

check the fuse for the fan. I don't know what number it is but i think it's a 30 amp one.

 

Yes the fuse its different looking than a basic fuse big and square with a window to see if its blown in the relay box/PDC 40 amp.

 

Called a Fusible Link
