1. OMG WHAT IS THIS GARBAGE CLEARLY YOU DONT KNOW THE FAN CLUTCH IS BAD NOT THE COMPRESSOR!

2. I didn't see you use any a/c oil that's how I was trained

3. Ray, before pulling the dash check the condenser fan to see if it is working properly. Hi side pressure depends on it. Great Video Ray as always.

4. You could do the fully illegal thing and swap in R12 if you can find it. 😅 I heard of a guy in Texas about 10 years ago that had a large stock of R12, that retrofitted all his trucks with it as soon as he bought them new.

5. 2016 Honda Pilot compressor broken .would not like to have dash remove is at all possible to have cold car again

6. There is a ccot that may have failed. The cycling clutch orifice tube regulates the flow of refrigerant to the evaporator. Too much in, it won't cool as well. Because you had the system open, you should subject it to a vacuum for 30 minutes to get rid of any moisture that entered. Under a vacuum, it will evaporate.

7. the truck is very valuable…..therefore, bit the dash and change it all back to NEW LIKE condition…..500,000 more miles to go!

8. You didn't charge the customer enough for this job😅

9. love to see you redo the headliner. new carpet could increase insulation. i would put some reflecting padding under the new carpet. while you are at it check with DMV to get the darkest tint allowed. Check with your doctor to see if they would put you in high risk for skin cancer and grant you an exempt letter.

10. Fix it ….labor is free….😬

11. I'm about a month late but I'd say start collecting everything you think you'll need for your project and do it when the weather cools down. Take a day and overhaul it.

12. Unless you have about $100k to buy a new truck, I'd definitely do the work on AC and interior. Looks to me like the engine and tranny are in great shape – and they're the whole ballgame…

13. I'll never forget the time one of those auto tensioners snapped while trying to remove a belt. Makes you respect finger position when doing belts.

14. Been driving in the UK for 50 years, don't think I've ever used air conditioning. 🤔

15. I checked the temp in my truck and it got down to 38 degree. Maybe the compressor needs to be broken in. What do I know, I just watch youtube channels.

16. My Uncle left me a truck just like yours except it is white and it has only twenty two thousand miles on it and it was a Texas truck. I also got all the maintenance records. He mainly used it around his farm and used on some trips.

17. Let it ride 🛻

18. Why don't you use a battery isolator that will keep them charged without having to flip a switch?

19. In this weather were experiencing. Id say get ready to pull the dash apart. It sucks alot but itll be worth it once you have a truck that has cold ac

20. I wonder if you put the recommended amount of freon in, if it will work a little better?

21. Go for the resto. Headliners, carpet, install extra wiring for the mirror cam etc. Don’t go installing all kind of goodies like the dual alternator and not have a fully nice truck. And don’t wait too long, the less you’ll enjoy it yourself.

22. We now have a pseudonym – it's cockney rhyming slang in the UK.

    For all those "Bob Dole's" out there negatively commenting on YouTube 😂😂😂

23. Considering pulling the dash: how long are you estimating you will keep driving the truck? If you realistically expect 10+ more years, then go for it! If you think 2-5, maybe just leave it alone. I expect you have other cars to drive when you don't need heavy hauling capacity.

24. Pull the dash now

25. Fix it

26. Before going through the full evap replacement, I’d at least get it up to the spec 1.6 lbs of refrigerant.

27. Rainman I have a question for you…. On my truck, Dodge 3500 6.7 Cummins, I can speed up or high idle the engine with the cruise control. Push set from idle then to increase idle bump the resume until you get the rpms you want. Can your truck not do this?? I thought this was kinda standard on vehicles because I've had others that are set up that way as well.

28. With the extra electric power of truck I would like you to add the artic air cooling system that installs in the intake run by a electric compressor it’s good for all engines especially diesels

29. Funny how when you forget a rag or something people jump down your throat, had it happen to me also. But one time rushing to get a job done I forgot to pick up a piece of test equipment, I know FOR SURE I left it in customer’s vehicle, called them and they knew nothing about it. $150 gone because they lied. This was also a customer I had for years and after that never saw them again. But I had the reverse happen also. Customer wanted to remove the heads for a valve job himself. He got it back together and ran worse then before. Brought back to me and I did a compression test and had zero on number 4. Removed the head and customer left a red shop rag in number 4 cylinder. That was a first for me. 😂🤣🤪

30. My 03 Super Duty 7.3 Powerstroke with 117K miles has been running with part time a/c , I don't have the money to fix it or know for sure what is wrong with it . I've been under the dash working on a couple other things and I ain't going there again . The heat here in central Arkansas is Hotter Hell , I'm 74 and as a retired mechanic I can't do but very little . I'll just have to live with it . Take care of yourself your only young once . Great video .

31. Electric condenser fan there also maybe to much oil in the system.
