I thought they both came on at once, >though they're definitly different styles. Depends on the year the car was made. My 1983 900S only turns on the right-hand fan when the radiator thermoswitch cuts in. The left-hand fan only comes on when the A/C is on. My 1985 900i is wired differently in that both fans come on together, then they turn off with the left one slightly delayed. I'm not sure if/when the wiring change was made or if it's part of the factory wiring or an after-sale modification. I've seen a document on Tom Townsend's website about how to modify the fan control wiring so both of the fans in my 900S will run when the radiator thermoswitch cuts in so I'll be looking at doing that before summer comes around. It's winter here at the moment. 8-) Craig. -- Craig's Saab C900 Page --> http://nospam/~c900 Sydney, NSW Australia Craig's Saab C900 Workshop -- For all Saab C900 Enthusiasts world-wide! http://www.nospam.net http://www.nospam c900nospam.apana.org.au Come and explore our site, and check out our web-forums, mailing list, etc.
