Honda Civic Evaporator Failures
Just wanted to share with some of you what I have been seeing in my area on a daily basis on the 10th gens (excluding Type R at this time). My area has not see the flood of condenser failures, it may be due to our climate (110F summers), but we have seen many compressor and now evaporator failures. From the compressors, it has been my personal experience that the front seal behind the a/c clutch is leaking. The compressor clutch will often appear oil soaked on the really bad ones, others will fail vacuum leak testing. The vacuum leak testing will keep failing until the compressor is replaced, I've had several whistle loudly when trying to evacuate them, usually a tell tale sign of failures.
I don't know what is going on with these evaporators but they appear to be deteriorating. When UV dye is added to the system, the evaporator looks to be very lightly peppered with the dye. I'm just letting this known in hopes that some of you that are having reoccurring issues can have this information. These chassis are having numerous A/C issues at once. Compressors, condensers, evaporators, etc. This repair is often much harder for techs to diagnose, requires very sensitive leak test equipment and is not visible without removing the part. Hopefully this helps out some of you and the techs fix your cars the first visit so you can get back to having fun again.
Repair requires removal of entire dash assembly down to the firewall. Failures have been on 2016-2019 so far, 15k-60k miles. The failures are very hit or miss, the cars vary greatly, no real pattern yet. The dark spots are oil/refrigerant from the system leaking.
I lucked out and got a new condenser for free. This A/C system absolutely sucks. Even right after getting the Condenser replaced and system recharged, the air really doesn’t get that cold.
It takes 15-20 minutes of driving to really cool down the cabin and the compressor to stop bogging the engine.
A proper air conditioning system should feel ice cold within like 2 minutes. I’ve been in plenty of cars 3x older than my car with A/C that is so cold it hurts.
I’m not paying 2 grand to get my dash completely gutted to replace the evaporator. I’ll suffer til I get my TSB letter.
Get worried people. This is a shit show. And expect dealerships to be booked months out doing nothing but fixing 10th gen A/Cs.
