Aircon/heaters

[Morphmite]

I have a question & hoping someone can help, i had someone come look at my car with diagbox (abs problem) but since then i have no heater or aircon. Would anyone have a setup for a c4 grand picasso mk2 as im getting my own setup now as twice ive had someone look at my car & its been worse after

It needs a proper diagnostic, preferably with Diagbox before we can assist, then put all the fault codes up here with the VIN.

Many systems are interlinked, so a fault in one system can have a knock-on effect with another.

Thank you for your reply, there are no faults in the aircon system. My new laptop arrives today or tomoz so will check but found no faults using a Snapon scanner

Not all readers can read all the manufacturer fault codes, as many are bespoke. It depends on the version and how up to date the software of your diagnostic tool is.

A fault with the systems you are describing will bring a fault code up. You haven't been very descriptive with the actual Heater / AC faults: Fan Blower working (if so on fast speed only or no speed)? Climate control panel buttons working? Screen Demister working? etc.,

Sorry for the confusion, i have nothing working at all but all works when i do a acuator test.

[Morphmite]

All buttons work on touch screen

Is it just that the blower motor is not running, but the actuators are working normally?

[Morphmite]

Yes that is correct.

So as the air distribution and air mixing flap reduction motors are working along with the controls, it sounds like the blower motor control module needs replacing. Caution here about replacing with a cheap part - they often don't work or have a very short shelf life if they do. Get a decent branded one, as your original has likely have lasted 9 years + now.

Many thanks for your info, is it an easy job to replace as im not too well in myself to get into tight spots any more & are they expensive to buy

Mike, those links are for the older MK I, not the B78 MK II Picasso, so won't have the same system or parts.

Oops, sorry for misleading.

Haha lol.
