Hi guys. Need a hand.

My climate control unit doesn't seem to be working properly. It was working fine on friday tho when I got my aircon regassed. Didn't drive the car on the weekend, removed the radiator yesterday to get it checked(was just the rad cap) and put it back today. That's when I noticed the following things aren't working with the climate control.

The fan doesn't come on when I slide the lever to any setting.
The Lighter is not working anymore
The airvent motor that changes the direction of airflow to different vents doesn't come on/change when I press the different buttons.
When pressing the buttons, the orangy/yellow light in the centre of them doesn't illuminate when depressed like it should.


However, when I press the AC button, the ac fan kicks in(in the engine bay)and the green light lights up on the button. When I turn the headlights on all the dash lights work and the climate control back lighting still works. The clock and radio still work as well without an issue as well as the demister and hazrds. I have checked the plugs at the back and they are all in secure. I have also checked every fuses under the dash and the engine bay and can't see anything blown but I'm not sure which feeds the units and the areas I have problems with(bar the lighter). The 3 plugs tho, the white feeds the lighter, the large brown feeds ? (Has 6 contact points) the other snmaller green plug feeds?? Also, whwre are they fed from? And do they utilize a relay or fuse or both?

Any assistance would be appreciated. Thanks in advance.
 
Not to worry, after checking everysingle fuse and relay with a multimeter, and checking the unit itself, by pure luck I found the problem. Just above the ecu there seems to be a plug for the grounds.- about 4 of them are there in total. 2 had come loose which was causing my problem. Big relief I must say
