I forgot to mention on your other post that when I bought a new radiator fan, I did not see an external mounted resistor on it. Maybe I got a post 96 fan who knows. I went ahead and installed the new fan though and the slow speed worked when it reached operating temp with ac off. Fast speed works when ac is on too. I hope I can help you with your factory fan but only thing I can think of is the motor could have two sets of windings. Only way to find out is to open it. __________________ 1996 Ti 280k miles and still going.... 1993 964 - holding on to this one 2001 Burban, 240k miles 2018 Suburban Z71 |
