As the title suggests, my 2014 Wrangler ac is blowing hot. Everything worked fine until the other day. I took off from a light and had to floor it when someone decided to run the red light and try to hit me. After that my ac started blowing warm air out of the vents. I figured it was just over loaded from the evasive maneuvers and was almost home so I didn't think much of it. I went to drive to the store today and lo and behold, it's blowing hot air still. Looking online, one of the first things suggested to check when the ac isn't blowing cold is the low pressure switch (two prong from what I've seen). However, the only switch I can find on my ac is a 3 prong switch, which I believe is the high pressure switch.

Am I missing something? Anyone have any suggestions before I hand to bite the bullet and pay someone to tell me what's wrong with it?

Thanks in advance.

You really need to go through diagnostic approach with the AC system. First things is to check and see if the ac compressor clutch engages. After that, I'd look at the pressures of they system. You need gauges for that. You can look at pressure switches but generally you do that after checking for pressure on the low and high side.

The main reason I am wanting to try to jump the pressure switch is so I can make sure that the compressor is coming in at all. Unfortunately I can only find the switch that seems to be on the high side with the 3 prongs.

I recently had to do this with my 09 Rubicon. Ended up juuuust being under pressure, enough for the fan to not switch on. Didn't have a leak, or nothing that registered as a leak. Just 10 years of duty, I guess. Took about .5 lbs, and got up to normal pressure, fan kicked in, cold air commenced. If you lived near me, I'd recommend a guy (cost me 25 bucks, and he taught me how to do it for myself if I ever want to rent the equipment from Advanced Auto Parts in the (hopefully far) future), but I see you're in OK. But, I'd personally start with pressure.

Just curious, did you smell anything when you gunned it? Anything chemically?

Yeah, AZ is a bit far to go to get it checked out. :) Especially without functioning A/C. :bop:

I don't remember noticing any smell or anything.
