Question:

1995 Cadillac Sedan Deville- is ther any way to check the power on my ac fan motor without taking it out?

i have a voltage tester but need instruction on how to use it. the motor supposedly tested ok before installation and i took their word for it without having it tested myself. any help would be greatly appreciated. Thank you, Princesscopperhead

Answer:

unplug the connection from the fan. put the two test leads from your multimeter to the two connectors on the wire harness you just unplugged, run the car till its warm, and see if any voltage appears on your meter. it wont register any voltage untill the car is hot and the switch makes contact to kick the fan on. maybe the coolant temp sensor is bad.....or fan relay/fuse
GROUND THE VOLTAGE TESTOR TO THE VEHICAL AND CONNECT THE HOT TO THE PROPER WIRE FROM THE FANS IT SHOULD WORK THIS WAY AS FAR AS TELLING YOU THE VOLTAGE
sure they could desire to. yet they do no longer seem to be human beings of religion. As they declare to be. they are human beings of concern. they could desire to no longer insure their church homes and mosques the two. yet they do. lower back a convention of no faith.
