996 fan resistor

[Steve up north]

Hi, I had to get a new resistor fitted last year because 1 of my radiator fans was not working, have an 80c opening thermostat fitted. now whilst normal driving temp gauge reads 90c, I had the car running for a while, temp at 90, no fans where working, air con was on, I suspect it is a resistor problem? is there anything to bypass the resistor, ideally something to turn both fans on, maybe fit a switch, will take it back to independent Porsche garage, but having the problem again in just under a year is frustrating

Hi, Andy
I found some info on the web,

Radiator fans;
Connect a wire to the ground of the 2 high speed fan relays located on the relay carrier located in the driver’s side foot well. The relays are #20 and #22. Feed this wire to where your switch will be located. Connect the wire to one side of the switch. Connect another wire from the other contact on the switch and then connect the other end of this wire to a chassis ground point.
With key on, this switch will now immediately turn on both radiator fans providing maximum cooling. When you turn the key off, the fans will continue to run for about 5 seconds until the relay shuts down. Your fan operation remains normal when the switch is off.
Engine Compartment Fan
Connect a wire to the ground of the relay located in the relay carrier behind the passenger seat, driver’s side. Relay #8. . Feed this wire to where your switch will be located. I simply fed the wire along the driver’s side of the car and under the door sill. Connect the wire to one side of the switch. Connect another wire from the other contact on the switch and connect the other end of this wire to a chassis ground point.
With key on, this switch will now immediately turn on the fan drawing air into the engine compartment. When you turn the key off, the fan will continue to run for about 5 seconds until the relay shuts down. Your fan operation remains normal when the switch is off. This mod helps keep the engine compartment much cooler when driving around town and is particularly beneficial to any engine that draws its intake air from inside
