not sure what year your car is but sounds like youve got it in d check mode,mines a 94 wrx and if you connect the two green connectors under the steering column then this will make the fans kick in and relays/solenoids go through there motions, not sure how the battery would affect this tho

charlieogden

would it help if i did a ECU reset? aggg its annoying me so much a "simple" battery swap....Keep the ideas coming....

Do the fans when the engine is running with the AC on, click on and off. On for maybe 10 sec then off for a bit?

.I was concerned when as soon as i switched the ignition on one fan would start straight away ,anyway i found when the aircon was switched off it didnt do it.It didnt cause me any more concern so havent payed it much attention since .
Sorry thats all i know.

Well thank you for your input people least it gives me some things to check.

Cheers Charlie
