I had zero problems with my stock fan / CCRM until I had the recall done. Once the recall was installed I had low-speed operation of the fan but as soon as the high speed fan was to kick on, the fan turned off.
I returned it to the dealer where they replaced the fan, CCRM, junked the circuit breaker add-in, and changed my thermostat. This got it working like it did before the recall was performed.
Six months down the road, my fan because intermittent. There seemed to be no ryme nor reason as to why it would and would not work. It'd crap out and start working again sometimes within minutes and sometimes the next day. It's been working fine up until today where it turned off and stayed off.
I searched the threads and decided to wire up the green / purple stripe wire to a switch that grounded out to kick on the fan. This netted me a nice clicker (the CCRM relays clicking), but no fan. I re-seated the plug on the fan - no joy. I checked and there seemed to be no power going to the plug at the fan. Upon further investigation it turns out that the +12v was working fine for the low and high speed posts on the fan, the ground was shot. The plug had actually burned and was starting to come apart. The wire itself looked to have gotten really hot and the sheathing had cracked away in a couple places all the way back up into the harness.
I was in a pinch to get the car on the road again (it's my only driver!) so I made up some jumpers to connect the high speed fan +12v and I ran a ground to the negative battery terminal for now. This ended up looking a lot like Dave88lx's alternator downgrade wiring job.
For the time being I've got the car drivable with the high speed fan coming on automatically as well as a manual switch to let me turn it on as I feel it needs it.
It looks like the root cause of my intermittent fan is the wiring harness between the CCRM and the fan, specifically with the ground wire. I'm hoping this is a section of harness I can buy to replace it, otherwise I'll try to find a good piece in a yard and go from there. I'm thinking that at least the plug for the fan should be available someplace.
I'll have to get a pic of the ghetto wiring job under the hood.
Hooking up the wire for the manual fan control was a piece of cake. It's gonna take me longer to mount the switch than it took me to locate the wire in the kick panel and splice in the tap.
I hope this helps somebody out. Tracing down our fan problems is a PITA
