That would be so awesome of you!
Im over fairly often actually.
Whats your schedule like?

Not sure yet. We're supposed to be at our church on Midway Road around 1030-1100 for about 60-90 minutes but that depends on when my daughter comes back up from West Palm. Not sure yet if I'm working tonight or tomorrow evening either, sorry. Saturday should prove to be more stable, I'll be at home until about 6 pm.

So I now have the enclosure wrapped up in Gaffe tape (much better).
I decided to pull back a portion to feel the temp of the Evap after touching the lines near the drier. Hi side is hot and low side is super cold. So thought to do the same with the evap.

So reached in and felt the evap on outlet side (red) had a ton of condensation and was much colder than what Im feeling at the vents. But also while on that side, I felt a ton of heat... hot rather. Fan had lots of flow on both sides (blue), but almost feels like I get more from opposite of blower motor; both were cool or cold.

Im curious to the the internal operation of the enclosure. Does anyone have a schematic?

Did someone cut away the plastic and expose the evaporator?

make sure the condenser is clean as well Bugs can get caked on and it does not take very many to hamper a/c performance....

there is some caked on my dads (not very much)

and it does not even work

all you get is slightly cooler muggy air even after having it serviced

after i cleaned my condenser it has better performance
since I noticed when if got warmer there was less performance

it gets cool with in 10 seconds of turn it on...:eek: good as new



also make sure both fans are coming on

Yes sir. Evap looks new along with blower.
I have peeked inside and both doors are closed on heater core so that is fine.
My money is now on the actuator that controls the where the airflow goes.
I made adjustments on the controller and didnt see it move. It also blows out of floor and vents at all times; never changes. Im wondering if there is a perfect point in the adjustment that causes terrible air flow... also being exactly there the actuator failed.

the rear A/C is independent of the front A/C(blower and actuators ) controller wise. . do check it (the only thing the front controls is the masterbutton power switch)


if it gets cold then the A/C is working and there is an issue with the actuators/wires or controller to the front... This would be the first thing i would do when trouble shooting.


does the outside temperature gage work? (on the mirror this is part of the A/C circuit )'


instead of throwing money at it


my dad wasted money servicing his A/C spent 200$
still was blowing warm muggy smelly soggy air

I fixed it in 5 min with some soap and a tooth bush.
