Hi Everyone, Brett from New Zealand here. I 've just registered having been on the site a few times. I have a 2001 Grand Vitara (Escudo). 2 litre petrol J20A 4WD auto.
Model is TL52W.This is a Japanese assembled "Helly Hansen" up-spec model. I am having problems with the climate air. Display unit flashes "auto" and pumps cold air in either A/C or heater mode. Vents/flaps all work. I believe there is a mixer flap door motor which may be malfunctioning. There is a buzzing noise when the heater is turned on and then temp display disappears and buzz stops, Any good ideas or repair manual sites? Thanks.

We have an SQ series Service Manual set for you. There will be subtle differences it appears, as you mention that your A/C has a read-out capability that Vitara's of this era do not have. Not sure what other differences there are other than you're right hand drive.

Is that the external temperature readout that you're referring to?

Perhaps post a picture of what your heater/ aircon control panel area on the centre console looks like- that should help work out what you've got.
