Ah, found the compatiblity list. The fan switch in the thermostat neck of a 94/95 is the same as in a
75-84 Rabbit
80-83 Jetta
74-80 Dasher

two part numbers at NAPA, both should be under $20
Beck/Arnley 2010809 = 92C switch/197F
Beck/Arnley 2011545 = 82C switch/180F

Found it in the FAQ actually, along with the claim that the factory switch is 109C/228F. OUCH.
I used the 82C switch in mine, and it worked perfect. The fans came on just as the thermostat opened up. Then the switch went bad in the middle of the winter, ack. So I just jumpered it and ran the fans all the time, now that it's warming up, time to get a new switch.

Can I assume that this is not good for a 97?

Not sure about a 97 at all, I really never had a chance to play under the hood of one, so I don't even know if they have the same setup for the thermostat neck.

For what it's worth, on my 97, which was having overheating problems for about a year, I've added a switch to manually activate the a/c fan. I'm not sure what temperature it automatically triggers at, but this way I can get a little extra oomph of cooling when I need it.

Manual says the condenser fan comes on at 225, read through the coolant temp sensor. Ther is no fan sensor in the radiator hose, so the ECU reads the sensor.

Looks like a new tap is required to fit a fan switch. Or use the hose from a 94/95? Are you guys sure these hoses have a separate fan switch? I would think the ECU would handle it as in the 97.

They do, the 94s and 95s have the 14CUX computer that is not nearly as complex as the 97s ECU.

Flow tested and rodded the radiator. All's good on steep inclines in 75 degree heat yesterday, second gear for miles at a time
