My a/c is not blowing cold. With manifold gauges I tested for leaks. Found a leak in each Shrader valve. Replaced the valves. I was surprised when my local Auto Zone gave me the two for free! Checking now to make sure the system holds pressure over night. If so, I guess my next step is to test all the a/c components? Love your videos and because of them I have hope that I'll be able to diagnose and fix any problem I find. Thanks so much from this 69 year old young lady in north Idaho!

This was very helpful. My 2013 Audi Q5 suddenly lost AC. I first tried to get a recharge can but AC pressure in the line was good. I did the multimeter test on the high pressure switch and got no continuity. I swapped this part out for a real German part ($80) and replaced it within five minutes. My car has a built-in check valve and that held in the refrigerant while I swapped out the switch. AC is back again without having to go to Audi Service unit and face a potential large diagnostic and replacement cost. Very much appreciated!!

4:17 the continuity mode will have a diode symbol, which is a triangle with a line on the right side. The symbol for a diode is a triangle pointing toward a straight line perpendicular to the wire. The orientation of the triangle in the symbol indicates the direction in which current is permitted. Just thought I would share this especially for those who need to test diodes in a circuit.

Thanks I have fixed car ac problems most were overcharged. 2000 Montero sport 160,000 miles sitting under a tree 3 years. Evaporator coil was dirty now I add freon and net day low side is high. Same ambient temperature temperature. It cools but not well. Have interior apart for better cleaning. Fan is extremely loud at high speed in cabin. Took blower and fan out, over 1/8 " end play . Also squeaking noise when I turn the motor by hand when pressure is applied away from the motor not loud. Oiled the felt at the rear bushing seems to help. About to clean the fan .

Replaced the AC clutch on a 1995 K1500. Still nothing. Finally checked the AC pressure switch and jumped the connection (paper clip the pins together). Fired it up and turned the AC on. Clutch engaged. Went out and replaced the switch. Had to recharge the refrigerant too, but that $20 part was all I needed. Highly recommend checking that thing first before more expensive and laborious work.

Hi there, so do i understand you correctly - having no continuity on the e.g. low-pressure switch, points to a bad switch? Did this check by myself today when garage quoted me a 700 bucks upwards for a new compressor. Belt and clutch are moving correctly when activating a/c :)

The flaw to the continuity switch test is a partial failure where the high side switch opens at less than prescribed high pressure. These switches are not expensive so replacement makes sense as long as u use a quality replacement part. I recently replaced a thermistor. The replacement had an impedance of 6.8 ohms when cold whereas the original was only 6.6 ohms. Cheap replacement parts can drive you crazy.

Great info, though if a multimeter isn't handy you can simply turn the car and AC on and unplug the low or high side plug and jump the (+)(-) sides with a wire. If the AC compressor turns on then you know you have a faulty pressure sensor/switch. But only do this for a few seconds or for testing purposes not as a bypass to make your AC work.

@cyberdemon6937
@cyberdemon6937 2 года назад
does the pressure switch for the high or low side ever fail in the constant completed circuit position? I ask because my compressor doesnt cycle it just stays on the ac blows only cold when the vehicle is moving or the rpms are rev due to cold start, once the rpm drop the compressor which is new makes a annoying sound the low side pressures goto 80 plus and the air becomes warm. this is a new compressor, also the expansion valve has been replaced. I'm thinking the new compressor is faulty however. we have checked and with the system dry no refrigerant the pressures between the high side and low side match. the reason the compressor was replaced was the original clutch on the oem compressor was broken, so i replaced it but the tollerences werent perfect so i got about 4000 to 5000 miles however that could have been because the expansion valve being a issue and the amount of parasitic pressure on the clutch to turn the compressor due to the pressures. this is on a 2015 wrx sti.
