I am new to this forum. I have a 1999 Jeep Wrangler Sport and recently my AC has stopped working. Does anyone have any idea of why this happened and how can i make it to start working again?
It's been sitting around for a year and recently (2 weeks ago) got new tires and alignment for it so i can start driving it. It drives perfect (i even drove it 4.5 hours straight), but I noticed the AC doesn't work anymore. I checked the coolant level and it was low so I topped it off just today. I will also get an oil change tomorrow. If anyone has any idea of why the AC doesn't work anymore, let me know. Thanks
I'm assumeing that you checked the heat and it is working correctly.
does the compressor come on in either the air or defrost (heat) setting? is it blowing air from either the defrost or floor vents in either heat/air settings?
You first need to find out if the compressor is engaging because if it does not engage then you will not get any cold air. If it does then perhaps the freon is low which can be checked with a gauge. The compressor is the round clutch type disk in the center of the pulley. Let us know what you find out.
if the freon is too low, the compressor won't engage.
You can use a wire to jumper the connection on the compressor to force it to engage and as long as its not locked up it will regardless of freon level. But I'd just check it with the gauge and start there. If you don't have one anyplace that can service A/C should be able to check your level for next to nothing.
Im would get someone to change out your o rings.
Its really simple if you have the parts. So dont let
them over charge you for this.Do this then have them install new freon.
While your at it change out the evaporater.( I believe this is what its called)
It will help make colder air.
I paid about 80.00 to get this done (labor) + materials
Tery, not the evaporator, maybe the receiver dryer or accumulator.
The evaporator is buried under the dash, it's big time job replacing that. And I know from personal experience on it.
The receiver dryer or accumulator, two names for the same item, sits on the firewall.
It's an easy item to replace, and yes it's job is to contain any moisture in the freon system. Replacing it, and the orifice are mandatory anytime the system is opened up.
Most likely the freon has dropped enough it won't allow the compressor to kick on.
It would be wise to have it recharged, and leak tested. And hopefully you don't end up like me with this week's project. Replacing the evap, dryer, orifice, after removing the dash. And yep it's getting a new heater core too. No way do I want to do that job twice.

God I miss that Jeep. Forgot the kinda Jeep, 80 SX4.
Sorry for the super late response. I went to the Crysler/Jeep Dealership and they were charging me $150 just to check the AC...so i left. So now i'm wondering where do you get this freon gauge? Could I get it like in Autozone and how would I hook it up to check??
Reality is wrong. Dreams are for real.
