My A/C quite working last year and because of health problems I hadn't done anything about it. Then, the other day I noticed that the cooling fan hadn't come on when it should have. Out on the highway I wouldn't expect the fan to come on, but I live on a one lane road and have to drive 10-15 mph uphill, so in hot weather it often would come on. I noticed the coolant boiling over into the reservoir after I stopped, but the fan never came on.

that seemed to be the same as my problem, but I replaced the two relays that they talked about and it didn't make any difference. When I tested them with a battery and an ohmmeter, they seemed to be ok, but I thought maybe under load they might behave differently.
Then, I tested the condensor fan relay (B092), which is a NO relay and could not get it to close, so that is what I am looking for.
I need either a B092, or the equivalent, if there is one. I notice that the diagram shows a diode in parallel with the energizing coil, so I don't want to use a generic NO relay, because I have read that the diode prevents voltage spikes which might cause damage.
