Been dealing with my fan clutch not working as it should for a bit now. With it being hotter here in Texas than in Phoenix today it is a bit of pain to have the AC quit working in stop and go traffic.
I was able to borrow a multimeter from my brother to do a couple of checks.
1) wires look intact for the circuit (no wire eating as is common)
2) I do have 12 V at the connector to the fan clutch (pin 6 I think)
3) The resistance across the fan clutch was 9.7 ohms. Problem is I don't know what it is supposed to be. Anyone now what the resistance is (Pin 1 to Pin 6)?
4) I was going to check the continuity of the line back to the ECM but what I thought was the C100 connector apparently is the C110 connector and I couldn't figure out the pinouts. (Maybe I'll try that in the morning)
I'm taking it in to the dealer to have them look at it on Monday, and want to be have as much figured out as possible, since I'm not in a position to swap it out at the moment.
I'm thinking at the moment that either the clutch is bad or the return line to the ECM is open.
