The fan on this one is not that bad. They come out as an assembly, so I am attaching the process.

Take a look at this info below in case you need it.

Thanks

I went to AutoZone, and they didn’t have any that looked like it would fit. I’m going to try Walmart next. I wish there was a universal way to attach it without a special connector.

Yeah. A universal may not work. Try this site.

Otherwise, the best bet is to try a salvage yard to find the harness and cut it off.

My dad's car mechanic was able to order it for me, so it should be here in a couple days. He gets my dad parts at cost.

Perfect. Sounds good. Thanks for the update. Just a note that I would suggest soldering the connector in and not using those wire connectors.

If this connection was already corroded, then we need to use the best type of connection so that it doesn't happen again.

Let us know how it turns out.

Thanks

So, I’ve been on vacation and ended up just ordering the parts on eBay. Anyway, when I splice these how do I make sure I don’t shock myself? If the car is off, is the battery off?

If you are in doubt, you always disconnect the battery negative cable and secure it away from any grounding point.

Unfortunately, it did not work, just the same whining sound as before. The new connector has thinner wire that does not appear to be copper.

Wait just a minute, one of them is working, and my air conditioning is working while idle again. However, the other has not come on. I did a lap around the neighborhood and have now parked and idling to see if the engine would heat up or my air conditioning would stop working. It has been almost 10 minutes and my engine temperature is still a little below halfway to H, so normal.

That is great. Most of the time if the A/C is on then both fans will be on but if the temperature is low then only the condenser fan will be on when the A/C is on. So, if that is enough to keep the engine cool as well then, the radiator fan will stay off.

Sounds like you got it so great work. Thanks for keeping us updated with this as you work through it.

Unfortunately, they stopped working. I’m very upset because I’m trying to avoid a giant bill that I simply don’t have the money for. Going to take a look in a bit at the wires

Hi,

I noticed you haven't been contacted for a couple of days. Have you been able to make any progress?

Let me know. Also, let me know what you have done so far to check the fans.

Take care,

Joe

Well, I have redone the wiring 3 times now and it keeps quitting on me. The new pigtail is beginning to melt now too.

Hi,

If the wiring is melting, either we are drawing too much amperage, or the wiring is a smaller gauge than needed.

The harness, which was used as a replacement, is it an original equipment part? Can you take a couple of pics of it and upload them for me to see?

Also, is the fuse for the circuit the correct amperage?

Let me know.

The harness for both fans was from the factory, both burned up after 10 years. The replacements I used were not original equipment parts, they were harnesses that I got on eBay. However, I’m still having the same problem of overheating.

Hi,

My biggest concern is the wiring you used. I read back through this post when Kenny was working with you. You indicated the wiring is not copper and is thinner. If I had to guess, I would say the new harness is the problem. If the wiring is thinner and not copper, there is a good chance it can't handle the electrical load. This can cause a fire. Have you checked for continuity in the new harness wires?

I had a new fan assembly put in and I’m still having the issue of only one fan kicking on. Relays and fuses are all fine, what else could be preventing the other fan from coming on?

Based on what I’ve gathered, I believe the fan assembly was not the issue at all nor was the wiring. I think the real issue has been a bad cooling sensor causing the radiator fan not to kick on and making the A/C fan stay on and overwork melting the wires.

Hi,

That is a very good possibility. However, the wiring shouldn't melt down. A fuse should fail before the wiring melts. If the wire gauge they used to make the harness is too light, it can do what you described and eventually cause a fire.

Is it possible for you to take a pic of the wiring and upload it so I can see what is happening?

Let me know. Also, let me know if the sensor takes care of the issue or if I can help in any way.

Take care,

Joe
