60 series detroit fan

couldnt he just pull the a/c fuse out to eliminate the prospect of it being the a/c/ high pressure switch ?

 

depends on if the switch s Normaly closed or open

 

i had the same thing happen on my Columbia with the Detroit 60 it was just the fan solenoid if that doesn't work might want to try the fan clutch

 

about the a/c switch is located on the filter drier .hi pressure switch and low pressue switch.talking about the fan always engage if the truck is O7 probably there is a open wire going to the fan solenoid,like they say only two types,air in unlocks the fan ,air in lochs the fan.

 

any thoughts on the reliability of a 2000 detroit 60 series?

 

I have a ghost light that comes on when the a/c is put on the high position. I can turn the motor off for about 5minutes and the ghost light will go away. put the switch back on high and the ghost light and the annoying sound comes back.
any suggestion that I can take care of this problem?
