ECO setting

When I press the third button from the right on my CCU, the one that opens the dash vents and turns the A/C compressor on, everything works fine wether on AUTO or HIGH or LOW setting on the fan. When I press my ECO button to keep air moving but without the compressor, it seems my blower will blow for a few seconds then shuts off. Shouldn't it still keep blowing but without the air compressor turning.

Yes, the fan should keep turning. What happens if you press the high or the low fan setting?

Does the same on the high or low fan setting. If I push the button that turns on the A/C then flip right back to ECO, it will stay on for a while then quit again. I did that 2 or 3 times yesterday until it finally stayed on for about 30 mins until I got home.

Sounds like a bad electrical connection in the ECO switch on the CCU.

I bet your right. My OFF button is very sticky and I have to push the ECO pretty hard and hold it for the OFF button to "pop" back out so the CCU will work. I read something on here a few days ago about reconditioning the buttons. I may try to find it again and give it a shot.
