Well after chainging the timing chain, water pump, hoses belts etc. I took it for a test drive and It ran great. Then I decided to clean off all of the oil and smuges from the job. I took it to one of those self service spray wash places and cleaned up the engine with the hi pressure spray. Now the A/C does not blow cold air. I looked for any connectors that may have been blown loose, checked for blown fuses, and looked for anything else out of the ordinary. Nothing, everything looked fine. Any ideas???
