Heater con­trol panel

Car Mechanics (UK) - - Tales From The Workshop -

The au­to­matic cli­mate con­trol on this 2005 Mazda3 was de­signed to be set at a com­fort­able tem­per­a­ture, then left to en­sure the in­te­rior of the ve­hi­cle re­mained steady. The sys­tem was work­ing, but the tem­per­a­ture could no longer be ad­justed – spin­ning the tem­per­a­ture con­trol dial did not al­ter the dis­play on the con­trol panel.

Af­ter a few sim­ple tests, it was ap­par­ent that the con­trol panel was the source of the prob­lem. A quick phone call to our lo­cal Mazda dealer re­vealed that a new unit came with a £500 price tag, so a sec­ond­hand unit was sourced for a much more rea­son­able £40 and fit­ted into the cen­tre con­sole. This in­volved the re­moval of the ra­dio and the lower trim to ac­cess the re­tain­ing screws.

The ra­dio and lower trim panel needed to be re­moved to ac­cess the fit­tings for the con­trol unit.
