CollumPlz Posted May 12, 2021 Share Posted May 12, 2021 I post way to much on this forum LMAO. I have an issue with the cooling fan not turning on which I have addressed in a previous post. I tried looking for things that were suggested but no luck.. The AC works but the engine fan doesn't turn on as it should. Engine temps are normal (about halfway) but the coolant is bubbling like crazy and is extremely hot to touch. This is while idling I should add. I am changing the coolant and the reservior tank soon as the coolant could be 10 years old for all I know.. but is there an issue with the fan? The fan turned on at full speed immediately after switching the engine off, but why not before? Is there two relays (low speed and high speed)?

I can also confirm both relays are working and fuse F4 that controls A/C and Engine fan is fine.. Quote Link to comment Share on other sites More sharing options...
Dan62 Posted May 12, 2021 Share Posted May 12, 2021 Remove the cooling fan resistor mounted close to the fan. It just unclips. Check the coil (resistor) is attached to the connector. Mine failed, one of the spot welds detached. Quote Link to comment Share on other sites More sharing options...

Because it turned on once the engine shut off but not while it was running? Quote Link to comment Share on other sites More sharing options...

Did you try bypassing it? 1 Quote Link to comment Share on other sites More sharing options...

I've got the fan off, picture below of what seems to be a resistor. Quote Link to comment Share on other sites More sharing options...

That's the worst one I've seen lol! Just need to unbend a paperclip and poke that into the plug terminals to bypass it. Quote Link to comment Share on other sites More sharing options...

I looked for replacements online but they look nothing like this one.. so I thought I'm looking at the wrong thing lmao. 1 Quote Link to comment Share on other sites More sharing options...

It'll either make the fan work more than it does now if the resistor is broken, or the same if the resistor isn't at fault, nothing bad will happen from bypassing it. Yeah, they should have a green insulating coating...either this one has all fallen off, or maybe it's a cheap aftermarket part that's been replaced before.

Once my new battery arrives I'll give it a go. Thanks 1 Quote Link to comment Share on other sites More sharing options...

Set to ohms and see how much resistance it has... If it's open circuit it needs replacing. Should have some resistance but I don't know how much off the top of my head.
