My 2009 F150 4x4 Supercrew AC compressor destroyed itself. Clearly, the low pressure lines are chock a block full of metallic debris/powder. Strangely, the high pressure side is visibly clean, although I'm sure it's also contaminated.

I've removed some lines for cleaning. But not yet the lines from the evaporator.

I'm concerned the evaporator is full of debris. I'll try various methods to flush it out, but I'd love suggestions. For those who don't know, the evaporator lines disconnect at the firewall. So I could fabricate something to flush from there.

Some treat it as a heater core and gently flush it with compressed air and the citric flush solution while in the vehicle, but I've read it technically needs to be taken out. I would personally try avoiding the latter.

Hook a hose up to the bottom line and run it into a container so you can catch and see whatever debris you've flushed.

That's a good idea. I'm not happy about wasting a week taking the dashboard out to replace the evaporator.

Debris is usually flushed out of a/c parts using mineral spirits, and finished with lacquer thinner or alcohol.

AC solvent and dry air is what we use. If it's as bad as you say every component under the hood must be replaced including the hoses.

I wouldn't be surprised if there was a filter (screen) just before the compressor inlet.

There should be a screen entering side of expansion value or orifice that should stop anything large from entering evaporator. Replace condenser is a must and only use ac flush. Autozone has the flush and the tool(loaner program) to put it in.

Denatured alcohol is what we used to use to flush the lines. Maybe this will work in the evaporator.

Does your a/c have an expansion valve ?
If it does, you may need to replace it also.
We never had luck flushing those out.

not as much as they used to. The special hoses and tight quarters make filters hard to fit.

Usually, it's the other way around: compressor dies and contaminates the high pressure side, requiring condenser replacement.

The evaporator almost never gets contaminated, unless the restrictor orifice is blown out.

Yes, whatever will dissolve the oil used.

That's the job of the receiver/dryer.

We do a lot of "completely blown" systems in trucks. In Florida, in the [censored] trucks, it's real popular.

Condenser is gone. Don't bother inspecting or cleaning. Just toss that thing.

Orifice tube or expansion valve is gone. Toss it.

Toss the receiver/drier too.

Flush using AC flush (most auto parts stores have it in a can, which makes it easy), then finish by flushing with denatured alcohol, and then a lot of dry compressed air.

The hoses should be fine, so long as they don't have any "mufflers" or filters.

Thank you for the input. The compressor discharge hose has a small accumulator/filter/canister on it. I'm sure it has debris inside. But I'm not sure what that canister really is. Maybe I'll cut it apart and find out.

The condenser has the R/D located on the inlet side, internal to the condenser.
