Just wondering if any body has had similar probs. If i am stuck in traffic the car risess in temp as the fan doesn't come on. also my A/c doesn't work and when i turn the ignition off the turbo fan doesn't come on. any diagnoses or advice?? by the way i checked the fuses near the serial port...

Anyone tried one of these to recharge the refridgerant in their air conditioning systems recently? Only started seeing them around in the past couple of months. Are they any good?:confused: I presume the recharge point is the silver little valve that sticks up above the radiator?

Does anyone know which relay cnotrols the a/c on an Ibiza cupra 20vt 2001 ?Also does anyone have a wiring diagram for thr Ibiza ?
