another a/c weird problem

[Sylvester]

Hello my a/c compressor and clutch is spinning but blows hot air unless i press the ec button then cold air comes blowing 40 degrees at vent, works great after that, also manifold gauges psi low side is 80 until i press ec button then 45 psi on low side gauges on a 100 degree day, high side not working i ordered a new hose arriving soon, anyone know what could be causing that 2000 mercedes e 320 thank you for your help.

Sounds like you are doing what you have to do to have cold ac at vents. I'm not quiet following what you are saying though.

"high side not working"

What does this mean?

Get a high side reading and post it. Is the fan in front of the radiator operating?

[Sylvester]

yes the fan is on, the high side on my gauges not working leaking air from hose, new ones should be here tomorrow. what do you think the problem is with my vehicle?

Leave the ac alone. It sounds like it's working fine.

thanks for the reply but my ac system is not normal, it doesnt come on at all unless i press the ec button are keep turning the switch on/off a few times, im trying to figure it out.
