I've noticed my fan doesn't turn on in my Spirit 80% of the time which causes the car to get hot real fast. I've tried getting it to turn on using the A/C but that doesn't work either.

Since it does work intermittently, I'm thinking it might be the relay going bad but I don't know where its located. Any help or suggestions on how to troubleshoot would be greatly appreciated.

All the relays are located on the fender-well near the ECU. It could be the relay or wiring gone goofy. Give those things a good checking.

I checked the codes and pulled up open or shorted coolant fan relay. Time to go pick one up. Thanks for your help.

Codes are nice that way aren't they?! :thumb:

Just swap it with another relay in the panel with the same numbers until you get one. I think the AC one would be a good choice.

Well I went out and purchased a new relay and popped it in. Then while in traffic, I noticed the fan came on. Good news, right? Nope! It was short lived as about 30 minutes later, the temp gauge climbed way up there and the fan was not coming on. I must have a short somewhere.

Check the fusible links and wiring to the fan.

Not a bad idea...but if you go that route use a thermal switch so you don't have to fool with it. Keeps the burden of operating the fan out of your mind and on the electronics.
