Customer states A/C not working well

[The_Eric]

Just finished up with a project and thought you'd all get a chuckle..

A farmer customer of mine has a 2015 F250/6.2 - he was dissatisfied with the AC performance. Didn't care about what it took to fix it, just make it work. He said it didn't blow out the vents very well and that it wasn't as cold as he thought it ought to be. The first thing that I noticed was a big hole in the HVAC box that had been taped up, then an aftermarket blower and wire repairs.. So I bought a used box which came loaded with all the motors and heater/evaporator core and wire harnesses. I noticed that the used evaporator had some junk in it so I cleaned it out, but that got my curiosity up. I pulled the original evaporator and holy crap! Little wonder it had poor performance...

I replaced the resistor with a new OE unit because to replace it normally, you'd have to pull the dash since it's on the back side of the HVAC box against the firewall and also a new OE blower. The blows cold and strong now!

Wow! Talk about a vehicle that could have used a cabin air filter!

Eric, good on you as you went the extra mile for your customer! Ever thought of relocating to N.C….?

That is incredible it has any airflow at all

Reminds me of the YT channel "Just Rolled In".

Did the farmer remove the cabin air filter or is the filter located downstream of the evaporator on that F-250?

I doubt that this vehicle even HAS a CAF. Downstream wouldn't make much sense, would it?

I have a feeling that the one on my 1995 Escort might have been like that when I got rid of it. I mean after 25 years and 265K miles with no filter why wouldn't it look like that?

Must be a road construction truck. Breathing nothing but dust.

I would think that all 2015 model year vehicles sold in the U.S. would have a cabin air filter. It makes no sense to position the CAF downstream of the evaporator; however, I have seen more than one vehicle set up that way, albeit from the '90's when they first started installing them.

The 16 f350 at my work does not have a filter

I am surprised by that...I guess Ford didn't think to design it in a HD truck. However, as the OP discovered, they are often used in a dusty environment where a CAF would help mitigate the clogged evaporator concern.

Super Dutys didn't get them until the AlumaDutys came out in 2017. Those use the same one as the 2015 generation F-150s as that was the first year for the F-150 to officially have a cabin filter.

It actually belongs to a farmer - when they're harvesting corn and/or beans, that truck is in some serious dust. Especially beans... Their dust is some nasty crap - that's mostly what plugged up his evaporator.

 

[PontiacHO]

We used to see similar problems with trucks that worked exclusively in our landfill. Also they got new engine air filters every PM- (4K or 3 months).

Or wheat or Hay, or alfalfa, or just the dusty roads in the field. I do see a lot of seeds though.
