Hey guys, awhile back I posted about an issue I have been fighting. I have a 2002 c240 with analogue climate control. things that has been changed and checked.

-new a/c compressor
-new climate control unit
-resync the flaps, no clicks, etc etc (no broken motor or arms as far as i know)
-a/c has been charged to factory when the compressor was replaced.
-checked all the fuses i can think of.

What else can i be missing?

Thanks in advance.

Yessir, just trying to locate one in the local area VIA members lol. how much does the dealer charge to get it scanned? 1 or 2 hour labor?

Dealers I talk to usually charge Minimum 1 hour labor for just hooking it up to star.

going to sound stupid but is there gas in there? Make sure a professional does it because you have to fill the AC systems by weight and not pressure. And also make sure the clutch is getting power when you turn the AC on. I would start with those two first.

Nothing is stupid sir,
It was recharged when the compressor was changed just a few months ago by a professional. Also, this car does not have a mag clutch on the compressor like the traditional AC compressor.

Update: its fixed. it was the temp/pres switch. The car ended up leaving me stuck on the side of the road (trans in limp mode) so ended up taking to a Merc shop where they ran a short test. front and rear sam's, temp/pres switch and gas pedal plus few minor stuffs were replaced and a bent wallet lol.

But thanks for all your helps!!
