Comment 1
with the a/c on the fans are not operational. I did notice the compressor spinning and it appears the a/c is pushing cold air (first time this week). The engine light is on...last time the engine light was due to engine overheating which it still does. -

NOW SEE IF THE RADIATOR FAN CYCLES OFF AND ON WHILE CAR IS SITTING THERE IDLING. THE COOLING FANS NOT WORKING WITH A/C ON COULD BE THE CAUSE OF NO COOL AIR.ALSO SCAN CODES AND POST -

Ok will do With engine idling the fans do not cycle on and off. The compressor comes on for 10 -15 seconds then shuts off...warm air coming out from the dash vents. Don't have a scanner for codes. Yesterday it was scanned and I was told the code for engine overheating is current. Can I short wires together to get codes? -
