The first repair - Toyota Supra, 3.0 liter, 1992

So, having thoroughly frozen during the driving of the car from Kharkov to Odessa, an unshakable decision was made to straighten the brains of the climate unit through surgical intervention, because he refused to respond to all options for persuading, stroking the dash, wiping the headlights. The decision was postponed due to a couple of warm days in which I could not deny myself the pleasure of riding without a roof.
So, I recommend it to all supporters. If the same problem appears - the first place to climb - remove the climate control unit. To do this, unscrew the rubberized lining where the cigarette lighter, ashtray, etc. is located. unscrew everything that holds the trim (6 screws if sclerosis does not fail me), then unscrew 4 more screws holding the block itself in the dashboard, disconnect 2 chips (light wide, it is usually the problem in it). Carefully disassemble the block. everything is taken apart with two screwdrivers. If you do it in the cold, I recommend bringing the block into a warm room, since in the cold there is an option to break off the fragile plastic. we look at the soldering of this wide chip and see cracks on it. This is a design flaw. In order to remove the plug, you need to make a lot of effort, so soldering does not stand up. There is a single fee Therefore, we take a soldering iron in our hands and carefully solder the connector. Along the way, having rung the cable, I threw it into the trash and soldered the usual IDE cable.
After these manipulations, my stove came to life.
