- Chasing down the reason that the ac clutch wont engage on my 1999 F-350.
hopefully this info will save some people a little internet search time.
Thanks for watching!

Thanks for the tutorial. Very informative. Nice to find a video that talks about the exact truck that I own....1999 F350 7.3L. Usually have to search forever to find something close.
Glad it was helpful! Thanks for watching!
Dude. You nailed it. I have a mint 97 E250 with an obsession for all things operational. I did tap on that low pressure switch thinking it was the high pressure switch. The recharge gauge was pegged until the system started again then read normal pressure. Plus literally for years was the AC clutch cycling. Thought it was spacer washers in the clutch at first, but that has already been replaced a few years ago. I can tap on that low pressure switch and make it work and tap on it again , or drive vibrations make it quit. Ordering a new switch from Amazon. About $15. At some stores there up to a hundred bucks.Ridiculous. But for each of mans vulnerabilities is a legal predator. Much appreciation for your vlog as it described this particular year or three with no relay perfectly. Thumbs up and subscribed !
Dude!! It worked. Tapped the sensor and I have AC. For the last 12 months I’ve spent over 1300 at 2 shops. And it’s a sensor!
Yikes!
Yup it worked for me. Tap tap clutch engaged. Thank you so much
My truck had the same issue except the terminals on the high pressure switch were corroded. Cleaned them up and it fixed the compressor to engage.
Great video - educational, yet not a snoozer...in depth and informative for those unfamiliar with the fundamentals, yet not a whole bunch of wasted O2. I dig it, well done my friend 👌 (Oh, and the "expands rapidly... ...back into a gas" word you were looking for is "atomizes")
Lol, Thanks
Bro you live next to my buddy Los cuñados food truck that’s awesome
I loved the video but I didn’t get off the couch till 10:43
Thanks for the great explanation:
My a/c system was replaced, condenser, evaporator, sensors, clutch, filter, accumulator except for the hoses, everything was flushed, vacuumed, and added 2 lbs of Freon but the system keeps cycling on and off, am I missing something???
usually cycling on and off means your system is low on refrigerant, a good set of gauges will show you if that is the case, or if the pressure is going too high for some reason, the gauges will show you that too. Hobo Freight has some gauges that don't break the bank.
what about a AC just shuts off completely, just sitting in park engine running and AC on working great, then it all just shut off, i dont have no power at the controls and have replaced all fuses and relay with new and still i turn the controls to on and max there is nothing, what else do i need to look for
I'd Start by checking the ac clutch, to see if it is energizing. if it is I'd look hard at the blower motor being bad. if its not I'd look at the switch and or wiring connections to it.
@10-4JackWagon thank u sir, it was the blower motor, thank you for helping me
@@Mike-jf4kf glad to help. do me a favor and subscribe if you haven't already.
What air filter are you running? part number?
That is a WIX 46637 which is available on Amazon for about 50 bucks currently.
Thanks for watching!
My 99 has no power in the hvac at all. It just quit one day. Could the relay under the hood be the issue with this?
Have you checked for a blown fuse?
@@10-4JackWagon i have checked all the fuses, none are blown
@SicilianSVT it's pretty hard to diagnose a problem over the internet. If your wiring is good, and the ac clutch kicks when you select AC : It could be the blower motor.
If the ac clutch isn't reacting and it did before, it could be the switch.
@@10-4JackWagon actually nothing is reacting. The entire unit has no power when i turn the knobs, which leads me to believe that its a relay
@SicilianSVT you could check by switching the # 31 relay with the # 30 in the engine bay power dist box. If it starts working, that relay was the problem. I'd also double check the #23 40 Amp fuse and under the dash the # 22 10 Amp fuse
