Cleaning Condensor

Make: GMC

I was attempting to flush out my condenser, but air will only flow one way, is that normal?

For the most part you should be able to move air in both directions. Odd you would have a restriction in one direction only!

The air flow method of 'flushing' a condenser is not a sound method to clean the unit. A liquid flush is necessary to properly clean the unit. Air WILL NOT remove debris fields from the inner tube surfaces of the condenser.
Had a tech call last week on a GM type condenser that would not flow air in both directions. The 'tech' seemed to think this was an accepted method to 'test' a condenser...yeah..right!!
This unit actually had the RD as an attachment to the condenser. The blockage was in the RD.
This condenser should flow air in both directions. Insure that the orifice tube is removed from the condenser outlet. This small orifice could be the cause of the 'one way' flow. Also when re installing this unit..keep in mind that the condenser can be installed upside down or the inlet/outlet hoses connected incorrectly.

I removed the condenser from the vehicle, and removed the orfice tube out of the line so that definitely was'nt a factor. Thank You for the responses.
