Renault Thalia A/C problem

[omglol]

I have a 2004 Renault Thalia 1.4 8V with faulty A/C system. When you press the A/C button, the light does not come on. Refridgerant pressure is OK, also diagnostics shows its OK and the clutch can be engaged via diagnostics. Does somebody maybe have wiring diagram?

that usually means faulty AC module (clima module)

HI,
on a Megane 2 it sometimes has the wrong type of heating set in UCH. For some reason A/C needs to be set to "normal" heating.
Don't know if that helps?

Had a Renault migraine 2 last week with a similar symptom. Has a burnt out fan speed resistor on speed no2. UCH did not recognise internal fan was running and would not authorise compressor in engine Ecu. Fan would only run on 3 and 4 but no compressor. Compressor would run on 1 and 2 but no internal fan. Simple fix new resistor pack ?25.
