1st Gen AC issues

So I have a 1995.5 tacoma 2.7L that has had a busted ac system since i got it. This summer i started working on it and replaced so far the condenser, receiver drier, and a few hoses. now it turns out that my evaporator is shot. or something within that assembly because when i loaded it up with r134 and started it up, it started shooting steaming refrigerant out of the evap case in the engine bay through the firewall.

 

So do i have to remove the dash to take out the evap? Or can it be done through the glovebox? im getting tons of mixed answers from all sorts of sources. I could not find a single write up for it anywhere


PS- In the few seconds before it started spraying r134 everywhere it actually blew cold for the first time ever. So its promising

 

No, you shouldn't have to remove the dash, just the glove box compartment.

Get a flash light to help you locate the screws. Replace the expansion valve as well, buy some nylog to coat the o-rings.

 

Nice to know it's easy to get to

 

Someone had to dive into it with there eyes closed.

 

Sweet thanks for the info. If I have time and get it done before school starts i may take pics and do a write up for those in the future. Estimates to get this done are through the roof. 500+$ no thanks

Yeah, my cousin had his entire ac redone and they charged him quite a bit, he's happy though.

 

Wow thank you! This helps a ton. now to order parts and hope it goes well First time this truck will have working A/C in over a decade

 

Eric the Car Guy is your usual mechanic guy like us DIY'ers. I believe he's doing less videos now, 'me time' I believe.

 

I hear AC Pro is pretty badass.....


Seriously tho, I just replaced my entire AC system with the cheapest package from Rockauto. For the 2.7 ---> https://www.rockauto.com/en/moreinfo.php?pk=3907692&cc=1364712&jsn=442

Came with nearly everything for the AC system - compressor, condenser, drier, oil and expansion valve - everything but the lines and evaporator. Took me about 4 hours, start to finish, including lunch break and a trip to the store. It's even easier on the 2.7 as the compressor is even easier to get out. Everyone will recommend Denso, but I figured I'd roll the dice on the cheaper compressor, we'll see.

The package ran me about $270 shipped, plus $130 to have the system professionally evacuated and recharged. For $400 total, I have new ice cold ac.

 

Potentially one of the easiest jobs you can do if you are even minimally competent mechanically. I did a short write up on evap core replacement here about a year or so ago. Replace the expansion valve at the same time (Denso is the OEM brand) as it will be attached to the core when you remove it and it's pretty cheap.

 

You guys are great! I've got the green fungus on the top of my pax side carpet, AC stopped working 6 months ago. Photos on the teardown of the evap on that Gen1? Exact same green fuz I've got under my pax dash. Gauge set and other symptoms match as well.

Started at the front, drier and new tubes, fresh condensor checks out. Compressor so far passing tests. Evap is next and I just know inside there is green fungus too. Kudos to the guys upstream that listed parts numbers for the Gen 1 job, I'll need a full set. And good tip on the clips on the engine side of the firewall, yes high line has nice alum fittings, low side has a very wimpy little plastic clamshell clip, gotta but a new one before doing the job. Will be tackling this in teh next 2 weeks, stay tuned.
