I am doing so diagnosing on my 95R. I can't remember the fan speeds from the factory on SN95 Windsors. What temp does the low speed come on and what temp does the high speed come on?

Thank you, Tom

According to the 1995 FSM, on page 03-03-5

Constant Control Relay Module

The Cooling Fan motor is controlled during vehicle operation by the constant control relay module (CCRM) (12B581) and powertrain control module (PCM) (12A650) which energizes the cooling fan motor under the following conditions:

*Engine temperature higher than normal. Cooling fan motor starts operating at 105*C (221*F) and stops when temperature drops to 94*C (200*F)

* A/C ON and vehicle speed does not provide enough natural air flow. Cooling fan motor start running at or below 69 km/h (43MPH) and stops at 77km/h (48 MPH)
