My radiator fan was making a lot of noise on high speed last summer. I
removed it, disassembled the motor and lubricated the bearings. You could
bring it to an electric motor shop to have them rebuild it.

Also, it is possible to lower the condenser and radiator enough to remove
the fan and shrouding without disconnecting any hoses. I didn't even jack up
the van, but I did use my hydraulic jack to lower the radiator/condenser/fan
assembly since it is quite heavy.

As far as I know, the radiator fan is only two speed. The high speed circuit
is controlled by the temp switch on the radiator. The low speed is
controlled by the A/C compressor and the radiator temp switch. The A/C
should switch on the low speed fan regardless of water temperature. R12
level shouldn't directly influence the operation of the radiator fan, only
the operation of the compressor and A/C system.
