Hope someone can shed some light. I have my C280 at the shop getting the AC system fixed, ie: new compressor, dryer, exapansion valve and charge.

Here is the problem: All pressures are perfect, compressor kicks on, the suction hose will not get cold. Tried another compressor to check if it was bad, still same condition.

If there was a restriction in the system then the pressure would not show correct readings so that is not it.

Can this be related to a bad douvalve or what? What else to check?

Thanks for the help.
