Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Probably going the change the ballast resistors on both fans anyway as it’s an easy job.

Coverage and how to read this overview

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.

1 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

986S (2000) decided to launch all of its coolant onto the workshop floor during the emissions test when it last went for an MOT. Noticed then that the cooling fans weren’t kicking in. Was about to swap the thermostat for a low temperature one anyway so did that regardless. Today I tested the fans/ballast resistors by removing the relays in turn and jumping the connections. We didn’t get any fan on left side/slow, but left side/high speed, right side/slow and right side/high speed all worked when jumped. I can’t feel any click from the slow relays when AC toggled on/off, but the AC needs regassing and I suspect there a ruptured connection or pipe somewhere but it’s not high on the list of priorities. Not sure if non-working AC will have any impact? Probably going the change the ballast resistors on both fans anyway as it’s an easy job. I’d appreciate any suggestions or ideas you may have. I have tried the search tool, but happy to be pointed towards any appropriate thread I didn’t find!
