Update. Found a procedure to reset the HVAC computer, no good. But, the parts have shipped from RockAuto and will be here this Saturday(16 June) instead of 22 June, may be able to take the truck after all.

Someone who lives in Texas and can swallow their pride for a few days for a car that has cold AC. It was 110 on Monday in West Texas. I'd temporarily drive a Yugo with AC vs my F-150 if the AC didn't work when it's that friggin miserable [emoticon]

My advice? Having done this a few times is to replace EVERYTHING!

If you try to flush parts, it can be impossible to be sure that you got all of the flush out. Flush is a solvent. Any left in the system will soon cause it to fail.

You need everything, including the evaporator and condenser.

Do it right, or do it twice.

Buddy had his AC go out. Compressor failed and put debris throughout the system. AC shop replaced everything, said they flushed it. Worked for a few days, failed again. More debris. After the third failure took it to another place. Said residual debris that can not be gotten out caused the failure. They replaced everything. Works fine after a year. Could be that he was unlucky? I do know of many home AC units that have failed and a flush and repair that has led to long term service. Internals are different.

Every time you do it, you are rolling the dice.
It is impossible to know for sure if it is clean, or if there is ..... stuff still in it.
It is a high stakes decision, as the price of being wrong can be astronomical.

Truck is cold again!
Got all the parts in Saturday afternoon. Replaced the condenser and compressor. Since I could not replace the evaporator and expansion valve without removing the dash(over 5 hours)I flushed them and all the hoses. Put a vacuum on it and let it pull for 30 minutes. Shut it off and let it sit for another 30 minutes vacuum never changed. Started charging up the system took 1 and 3/4 cans of Freon (22ozs). How's that song go "Cold as Ice" The compressor blew an internal seal.

Just as a side note.. I had a buddy who's son was a poor college kid. The compressor quit in his sons car so he drove down there (Wilmington NC) and replaced that compressor in the rain. He didn't draw it down or anything, just added refrigerant. The new compressor lasted one year almost to the day.

Evap is not hard. I have a flush can that you pressurize and use a/c flush. It's a lot better than taking the dash all the way to the fire wall and then having to take the HVAC box completely apart to just get to the evap to replace. I've done it because of evap leaking but if it's not leaking I'm not changing it out.10 years of doing this with zero issues.
