Perhaps, you mean as to bypass the pressure switch ? This is what I aimed to do, but if you want to actually just make the pressure switch always be on, you could do that. I don't know how, but I'm sure it's possible, though that may have other implications I'm unsure.
Hi, thanks for the video. I have a bad IHKA and am unable to get an aftermarket in my country as the e36 320i 1992 is regarded as an older model. I have disconnected the module and i want to find a way of starting my ac, so i bumped on your video. Ideally, the compressor should spin intermittently but in your video it wasn't show. So i was wondering if i can rewire the pressure switch as a trinary connection to power the clutch and the condenser fan. I would appreciate you guidance and explanation.
What you wish to do is definitely possible, though I recommend finding a way to turn the compressor and fan on individually first. Once you know how to configure them as always on, you can then figure how to wire the pressure switch.
Unfortunately I currently don't have the info to help you and I am away from home for the rest of the year, so I can't go and test these things myself.
Thank you so much for the reply. Getting the module to be shipped to my country is a problem. Looking at the pressure switch and the trinary, both looks the same but don't know if it would function the same way. And do you have an idea which wire is the signal from the module to the pressure switch. Thanks once again
Hey could you help me out, my ac compressor is good, i tested it like you did it with the positive wire of windshield washer motor it clicks but my aux fan or condenser fan not spinning, any idea that may leads to why it's not working? I tried to swap 2 relays on low and ac relay nothing happens.
Do you know if there is gas in the compressor? If the gas is too low from a compressor leak the electrical system won't turn the system or the aux fan on
Also your fan might just be broken so you might have to test if it works at all. Otherwise if it's just not getting a signal I'm not sure how to fix that as I haven't tried. My aux fan seems to turn itself on intermediately so I didn't have the same issue.
I havent checked the gas in the compressor, but i tired to connect or jump the pressure switch wires the aux is working so could this be the pressure switch is broken? Or any other reason?
Yeah it produces cold air. I'll try replacing pressure switch i hope it's the one causing this problem. Because if it's the wiring daaamn E36 wiring is nuts.
Yes, this is a possibility however only if the condenser over-heats. Turn your car on and see if the condenser fan is turning on. If the condenser fan isn't turning on, then the condenser may over-heat. For my car, I didn't have any problems with over-heating as 70% of the time my condenser fan would work, or I would be driving mostlyfast enough for the air to cool it down.
Any questions let me know! If you prefer, shoot a message on Instagram @max_gadd. I have contact info on my youtube Channel info page as well 👍. If you reply to these comments that will be fine as well.
the wire came loose recently but AC doesnt seem to be the problem. ill reattach it soon. its definetly not a permanent fix, but i dont drive much so its fine.
Im having some issues here, so i just discovered the pressure switch socket just plugged out, i wonder what original cable for pressure switch?
Unsure sorry, id have to investigate
Would it be possible to wire in the pressure switch?

Do you have an electric condenser fan ?

You may be able to find a module on ebay, though i assume ebay is not an option for you ?

@@_J20_ yeah perhaps, when you jump the wires does the AC produce cold air ? If it's not cold then could be a gas leak
Yeah it produces cold air. I'll try replacing pressure switch i hope it's the one causing this problem. Because if it's the wiring daaamn E36 wiring is nuts.
Im having same issue with my e39 would this cause an over pressure situation and blow the lines?
Yes, this is a possibility however only if the condenser over-heats. Turn your car on and see if the condenser fan is turning on.

Has your ac system ever given out on you with this method?
