NathanSmith Posted March 30, 2012 Report Share Posted March 30, 2012 Ok after extensive research, I have found that relay 39 AND 40 Work togather in operating the LH cooling fan, What i am still dumbfounded on is (what makes the RH cooling fan run in high speed?) Looking at the wireing diagram it looks to me like the RH fan only runs in Low speed. when it gets ground through relay 39. in high speed operation its path goes to the Lt Blue wire to B+.

JimD Posted March 30, 2012 Report Share Posted March 30, 2012 .... What i am still dumbfounded on is (what makes the RH cooling fan run in high speed?) The speed of the RH cooling fan motor is determined by the position of the COOL FAN S/P relay. The S/P part is for Series/Parallel. A defective COOL FAN S/P relay could easily mess up the operation of the RH fan motor. Jim Drive your car. Use your cell phone. CHOOSE ONE !
