First post guys. Appreciate any feedback. We just had the ac evaporator replaced and everything seemed fine and operation as normal. The wife was on her way home last night from Orlando airport on the interstate when the expedition totally lost all power, shut down, no dash lights, no brake lights or anything. Thank God she was able to safely coast off the shoulder without getting crushed. After stopping, the dash was lighting up every possible error available but she had no control while it did this. After sitting for a moment it started back up and operated as normal for the remaining 30 miles home. This has never happened before. I can't help but feel like something from the evaporator replacement, which requires complete removal of the dash, has something to do with this. The computer clearly lost all power and shut down the vehicle. She's done with it after this and lost all confidence in it's safety with our 3 little ones always in the car. Unless I can find a clear culprit, I'll likely be trading it very soon. Anyone who has some insight would be greatly appreciated.
