Hello all, I bought a used Ford Escort MK7 tournament 1.6 16V last week. Unfortunately I did not test the air conditioning during the test drive. But one day later. The air conditioning did not cool. So the “climate check” was brought. The system was refilled (but I was pointed out that only a little bit wasolted) After that the air conditioning still didn’t run. The good man in the workshop still ran a bit in the engine room. Only on the left side (i A connector on the left side was quite oxidized, it was cleaned. But it didn’t do anything. Then there was still a bit of quilting and a bit of making around there. Suddenly the air conditioner jumped on and cooled excellently. I drove home pleased. I only paid for the filling of the system. The next day was already shift in the shaft. No function of the air conditioning 🙁 I have the oxidized ste cker already kicked out and all cables soldered directly and sealed with shrink hose. (cable colors = purple, purple-black, brown, brown-black) I turn on the air conditioner lights up the green lamp and the fan also starts, but not the compressor. Does anyone have any idea how to proceed ? Thank you & all of you a nice evening. Maik
