I'm still running the original factory fans on my car coupled with Dave McKeen's light blue fan fail relay with the two small fuses on the top.

Took the car out Saturday for a 400+ mile round trip cruise down the Natchez Trace Parkway and noticed about an hour into our trip, the fan fail light on the dash panel starts flashing really bright (it does has LED's in the panel) . Pulled over on the side of the road and crawled under the front end of the car and BOTH fans are blowing just as they should be. Figured it was a glitch in the system somewhere.

Stopped for gas in Florence, Alabama and when I restarted the car... No flashing fan fail light. 30 minutes later it starts flashing again. I ignore it this time because I can hear both fans running. The longer we drive, we see the fan fail light getting dimmer. By the time we got home it was still flashing, but just faintly visible.

New fans are on my list for this year, but what gives with the bright flashing and dim flashing?
