Hello, I drive a Mazda 626 2.2i GD built in 1990. Well, suitable for the summer, my air conditioning is on strike. Together with a cold chill I wanted to refill the system, because we suspected a leak. Unfortunately, the system did not suck in a refrigerant. The KAB meant that the system is probably clogged at the dryer or in the capillaries. Now I wanted to open up without the circuit, because the system is still filled with R12 and this expert has to be disposed of, which So I screwed on the glove compartment and now I can’t get any further. Behind the glove cover is a black box in which, to my knowledge, the capillary can be found. But unfortunately, I can’t open the box. Now to my question: Can I open the box only in extended condition? If I’ve seen this correctly, it’s a screw-down of the back and back cooling pipe in the engine compartment and thus an opening of the cooling circuit. necessary, right? Where can I get spare parts for my air conditioning (such as capillaries, dryers…)? Thank you for your answers in advance. Greetings, mriedel35
