Re: Freshly repaired A/C system short cycling.
I will try that, though I’m already pretty sure this switch is what triggers the computer to shutoff the ac. Its the only one I havent tried yet since its so far up the dash …. Idk if its a transducer though

Re: Freshly repaired A/C system short cycling.
I watched your YouTube links. 13.4Oz to others saying 15Oz (AllData) confirms. How much oil is in the system? It needs to be as close to OE as possible, no guessing. If in a shop with a recalimer. I would add some refrigerant, R134a, of course. It looks low to be from a keyboard away. I don't know ...

Re: Freshly repaired A/C system short cycling.
No, I haven't looked at the clutch gap. What kind of behaviour could that cause ? The compressor was replaced, I just installed it. For the pressure readings, I would guess it's the low pressure. It triggers at the pressures i've mentioned previously (20-25psi and 200-210psi). I'm getting those read...

Re: Freshly repaired A/C system short cycling.
Best Practices suggest replacement of both the Receiver/Dryer and o-rings. The desiccant in the R/D captures and retains any moisture that's introduced into the system and can't be rejuvenated. You might be able to re-use the o-rings if they aren't deformed, nicked, or torn. Give them a thin coat o...

Re: Freshly repaired A/C system short cycling.
Could the problem be with the expansion valve even though it's new? If memory serves, a few different TXV's are available for your car depending on the engine size and model (DX, EX, EX-L LX etc.). Wondering whether you got the right one. Actually, if I replace the TXV again, should I replace the d...

Re: Freshly repaired A/C system short cycling.
Hello John, It does seem like there are multiple models for the 2012 Civic. I checked and the OEM reference number for the UAC EX10411C TXV I ordered is 80221-TR0-A02. This OEM part seems to fit my 2012 Civic EX 1.8 when I look it up on TorontoHondaParts. There is also the 80221-SNA-A01 that is supp...

Re: Freshly repaired A/C system short cycling.
I used Brake Cleaner with a flush tool plugged into a compressor. Did 2 passes of brake cleaner then used compressed air to insure most of it was gone. Let it dry overnight and next day pulled a 1:30 vacuum.

Re: Freshly repaired A/C system short cycling.
Hello John, thanks for your response. First, temperature was around 80F and humidity 80% for all my readings. I did try and run the system for 2 minutes at 1500RPM but as soon as I rev up the engine the compressor starts to short cycle. I can't get it to stabilise because (I assume) that the system ...

Freshly repaired A/C system short cycling.
I recently proceeded to repair my AC system on my Honda Civic 2012. I replaced condenser, dryer, compressor and expansion valve. A/C has been working well except almost always short cycling (about 20 seconds on then 3 seconds off). When it comes to filling this car with refrigerant, i've found confl...
