Post All lights Flicker when A/C turned on.

My 97 E320 has a problem with lights whenever the A/C is turned on. All of them start flickering and while driving the transmission acts up and starts shifting hard or in a shattering reaction. Anyone knows whats wrong? Is it the alternator or the regulator not handling the extra load of the A/C?

Check all

power harness fittings and the alt harness.If it were a 96 I'd say check the wire harness. Check it anyway

Flickering lights

Thanks Ohlord for your responce. I checked my harness connectors and they seem to be OK, I started the car, turned on the A/C and as soon as the A/C fans in front of the condensor start turning, the lights start flickering and when the fans stop, the lights go normal. Is there a relay or a resistor connected to those fans or is it the fans themselves going bad? Anyone knows?
