AUX fan

Hey all. On a 98 when should the AUX fan kick on? Tried turning on the AC- no fan movement. Defrost, maxed heat and blower fan cranked. Still nothing. Never had any overheating issues. Just wanna know. Thanks

Thanks guys! I left the XJ running in my driveway while I waited for replies. Never passed 210 the hour I let it run.

Is there enough freon in the system? iirc, the ac fan comes on when the compressor cycles. If the freon charge is low and the compressor doesn't start, the fan will not come one.
