She's a 1990 900 T Cvt. New to me, just going through it this week.
When the car warms up enough for the fan to kick on, Both fans come on for about 10 seconds then the passenger fan stops and the drivers side keeps going for another 15 or 20 sec's then stops.
This repeats itself about every 30 sec's
I checked the relay and it was a different one than what my 90 SPG uses. So I swapped it out for the SPG relay (Which worked fine in the SPG)
and it did the same thing except it would almost make the engine die when the fans came on.
So at this point Ive cleaned all the grounds, Haven'T had time to try the SPG's relay again but will tomorrow.
Why would both fans go on instead of just the passenger side fan?
Anyone got any ideas?
Thanks
Jim
