Pee Gee Posted December 7, 2021 Share Posted December 7, 2021 Hi all, I've had my 2015 CR-V idtec (2.2) since April, and as the weather has got colder the dash makes some very strange sounds that last for about 45 seconds, this is without starting, just opening the door and sitting down. Does anyone know what it is? It's some sort of electrical sound and seems louder the colder it is! Thanks. Phil. Quote Link to comment Share on other sites More sharing options...
Trevor Posted December 9, 2021 Share Posted December 9, 2021 It could be the heater flaps re-indexing or other system relays (timer) to prime the engine (fuel, intake, etc) Quote Link to comment Share on other sites More sharing options...

Thanks. 1 Quote Link to comment Share on other sites More sharing options...

Thanks. And yesterday which was a mild morning the sound was noticeably quieter, so definitely affected more by the cold. 1 Quote Link to comment Share on other sites More sharing options...
Trevor Posted December 15, 2021 Share Posted December 15, 2021 Tolerance clearances have changed with the temperature I guess.....at least you'll know how cold it is by the level of noise the car makes 🙂 Quote Link to comment Share on other sites More sharing options...

Good idea, I may just try that. 1 Quote Link to comment Share on other sites More sharing options...
Trevor Posted December 15, 2021 Share Posted December 15, 2021 Silicon spray is quite safe to use unlike WD40 as it is not oil based and you can liberally spray it under the dash 1 Quote Link to comment Share on other sites More sharing options...
