I’m trying to troubleshoot why the radiator fan right in front of the header is not coming on either when the cars warms up or if I have the A/C on. How do you know if the relay is good or not? TIA for your replies.
Anyone?
I think I have a similar problem… first of all, I would check to see if there’s voltage at the connector for the fan…(the green one on top of the fan) It could simply be a bad fan. I could also be the temp sending unit, I don’t really know how the cooling fan is working, but on my old car, it simply was a thermo-switch… and it could be the relay, which is easy to check by probing the signal… if there’s a 12V signal coming to the relay and the fan isn’t working, the relay is bad!
HTH!
