Removed unit
Replaced expansion valve
Replaced receiver dryer
Cleaned evaporator
Put it all back together
Blows nice and cold, and more air flow



How do we arm the other 11??

how hard is it to pull the evaporator to clean? Evacuate system, disconnect hoses, glove box and remove the under dash unit? I know it's not environmentally friendly, but can you open the system at home?

I'm sure mine looks the same after 200,000 miles.

Not too hard. Basic hand tools and wobble 10mm socket for bolt on the top.

A proper evac is necessary

If it ain't broke, don't fix it

You could, but you'd have to replace the drier, then reassemble, pull a vaccum for at least a couple hours, then recharge...


Is it possible to clean in place? I clean all my HVAC coils in place on all my units. More of a pain, but it's easier than pulling the system apart and much less chance for contamination (the refrigerant oil is very hydroscopic)
