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.
Leading evidence: 'Install last year' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check fan resistors' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

When you turn the key off, the fans will continue to run for about 5 seconds until the relay shuts down.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

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 Steve
The following will give you all the info you need with regards to there operation and the wiring diagram may help you.
Good luck

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
