Common leaks on your Ho are fittings, low pressure switches, and condensors. Hoses have a habit of leaking as well.

And by fittings I mean the service ports.

Just charge it and wait for the flashing light. Then check for leaks if nothing wet with oil is jumping out at you.
Dang, you can't make the overhead that way.

Dean, at $3.80 a pound, I call it a wash. You can make a lot of people really happy by not nickeling and diming your customers.

Guess what I charge for tire repairs? I tell my people either gratis or $400. All seem to take the first option.

And at an average $550 for a compressor and up to $800 for an evap, I'll give you the first shot of freon for free.

Re: 2014 Tahoe A/C

Sounds like me.

Some of my friends in the business use to tell me I was crazy for not charging to plug in a cord, flip a switch or do something simple like that.

A lot of times I would tell customers how to do something simple over the phone themselves to save a service call charge when I could have sent a service tech to do it.

Re: 2014 Tahoe A/C

I will add to look at the shaft seal on the compressor. That will get slung around some, so if you see dye splattered on your inner fender, start looking closer at the compressor.

Re: 2014 Tahoe A/C

Well, giving the system a little charge didn't last too long. And we only had an 80 degree day yesterday, and that was enough to get the wife, 2yo and 4yo complaining, making for a brutal car ride. So I climbed under the hoe with my UV light when we got home. Sure enough, found dye at the passenger rear, where there is a hard bend over the axle. I'll have to double check, but I think is was the larger line, the low pressure return. What do you think I should do? I can't do a splice since it's at a bend. Then I see Dorman make's a repair kit to replace sections with the hose and compression fittings for $50. I also see there's a full replacement with rubber line, but that's $350. I assume a shop will want to do it right and replace the full hard line front to rear and that will be $$.

Re: 2014 Tahoe A/C

Also look in the corners of the condensor.They leak there. Gm replaces a lot of those. Radiators also.

Re: 2014 Tahoe A/C

I looked around the compressor and looked at the condenser best i could. I'll take another look at the corners if possible.
Yeah, i replaced the rad a couple months ago. Geez, i had less problems with my previous 15yo tahoe

Re: 2014 Tahoe A/C

Ok, here is my advice, If you are planning on keeping the Tahoe for awhile, get the lines and replace them. If you can't do it, maybe find someone in your club if you have one. Possible to do at home?? If not planning on keeping it, do the splice kit, Good luck!!

Yeah, I agree. I just got the truck last year and plan on keeping it for awhile. I took it in today to get an estimate. And like someone said, the lines come in two sections and they need to be crimped or coupled. I don't have the tool for that. Eh... we'll see what they say

Re: 2014 Tahoe A/C

Well, after 4 calls, them telling me they couldn't find the leak, it didn't instill too much confidence. And once they find it, the call and tell me the hard line comes in two pieces and they don't have the tool to join them. And i have to take it to a dealer.
Good times...

Re: 2014 Tahoe A/C

I couldn't get an appt at the dealer til tuesday. And I need the truck this weekend, so I had to use a little redneck ingenuity. I pulled the plastic fender well off and the lines are right there above the frame. Rotted pretty bad in those plastic retainers. Maine must us acid to get rid of the snow on their roads. Come to find a second leak hidden under the other plastic retainer. So I cut some 3" pieces of 3/8 fuel line and wrapped the ac line and clamped with some hose clamps. I charged up the system and no leaks. Now it makes me wonder how my coolant lines and brake lines look under these retainers ....

Re: 2014 Tahoe A/C

I replaced both the brake lines and fuel lines on our 96 Tahoe a few years ago for the same problem. Started with the brake lines and found the fuel lines corroded as well when I removed the fuel tank to replace the brake lines. We lived in Maryland at the time!
