Here is the relay numbers
30 - power
87 - to the fan
86 - ground I think / Negative
85 - 12 volt power source.. from sensor I guess.. or computer
I've tested the bridge from 30 to 87 and the fan comes on
I've tested the bridge from 85 to 87 and the fan comes on
I've tested 30 and get continuity
I've tested 86 and get continuity
I even changed the relay but still no go..
what am I missing?
I was thinking and I'm going to see if I can check it today but I can seem to get a connection from 86 when I have the tester connected to the batteries positive post.. and I'm thinking that maybe I should.. to verify it is grounded ok..
I'm not sure how to check it but I guess taking it apart may be a good start... and see whats happening under..
any suggestions?..
I'm about ready to wire in a whammy switch to turn it on and off as I need it..

What year is your car and how are you waiting/trying to get the fan to turn on? It should turn on when the A/C is turned on (as long as the compressor engages) or when the temp needle goes past 1/2 on some models and 3/4 on others. Replace the engine coolant temp sensor if you haven't already done so.
