The reset works as follows: With the key in the ignition and in posistion 2 push both the defrost button and the recirc button (at the same time) for five seconds or untill the led lights in those buttons begin to flash. Wait for 30 seconds or untill the led's stop flashing. Switch off the ignition. Check the evaporator temp sensor and pressure sensor for correct functionality.

check fuses

I recently tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master. It would'nt move forward or reverse, engine was good both solenoids for forward and reverse worked, but still couldn't diagnose the problem. I don't have much technical knowledge but I just followed it step-wise, and now it works perfect! covers wiring, codes, diagrams, torque specs, PCV, everything got it from www.reliable-store.com

Put in a replacement radio - electronics are a problem

it sound like a relay for the windows have gone should be in the fuse box this should be if right hand drive but should be the same if left open bonet as you look in it will at the top left hand side of the engine black box take off the cover all fuses and relays are numbers just pull the one out for the windows also check fuses as well another possibility could be the window switch cluster around gear stick but this is unlikely hope this helps ivan

A/C is cold or hot?

Alternators are expensive parts, especially at dealerships. I'm inclined to agree with you, they should have got it right the first time. No shortage of tools with them, but in fairness to them, intermittent faults are the hardest to detect. They might come back and say you need a new battery, although it does seem odd that a little testing the first time might have caught that. Those are the two main items in the start circuit you are having trouble with. Well, the battery, the alternator, the starter and the ignition switch, those four items are the main parts of the start circuit. But with a good battery and an alternator to keep the battery charged up, it will crank over every time. Ideally, that means it will start and run.

what is the problem

U have a Mercedes and the dealer will rip you off for sure. That is a Mercedes thing. Unfortunate thing is that the car has class A engineering but of what use is it when the reliability is below par? U got the correct info on the culprit but do you want to pay the price?!?!?!!??
