A couple of questions.
Two Fans, one larger then the other. Which one is for the AC and which one is for cooling when car is not in motion?
Is testing these fans as easy as putting 12V to the Unplugged connector? Neg to Black wire +12 to Blue one?

The Fan thermal switch is not on the radiator. Where is it physically on the engine?

On your 1999 4WD LXS 4AT CRV, the larger fan is the radiator fan and the smaller one is the AC condenser fan.
Yes, you can check a fan by unplugging the fan connector and supply 12v to it's connector.
One radiator fan switch is on the thermostat housing.

You can usually test for a bad radiator fan switch by unplugging it at the thermostat housing and putting a jumper in the connector. Turn the ignition to ON and if the radiator fan comes on, it is a bad switch. If it doesn't then it could be a bad fuse, a bad fan, a bad relay or an open in the wiring.
Both fans work off relays and both should turn on when the AC is turned on.

You can dl a shop manual off Ebay, etc for under $20 or perhaps for free if you search the Internet more.
Electrical diagrams are also available for free if you search.

Thanks. I assumed I could put voltage to the fans direct but I thought I'd check. +12 to the fans .. no spin. I did a little tap on them and they try to rotate for a second. So even though theyre not seized, there is an internal electrical issue . Probably worn brushes. Yup, I see the thermal switch at the t stat Housing. thanks

Aftermarket fans on Ebay, etc are a hell of a lot cheaper than OEM.
At least on your CRV, they are pretty to replace, not like on my '03 Ody.
Getting a shop manual for your CRV would be well worth the money. I got one yrs ago (.pdf) online for free, but I don't remember where.
Here is a paper one for around $22 inc shipping:

I just saw it while doing a search. No personal experience with it.
