a/c questions.
ok so today i got a few a/c lines replaced they were leaking and a new condensor canister and charged up. the guy tells me i have a slight leak in the evaporator core but it should be fine.
so i went home and it blows cold oh yes its so nice then my compressor starts to kick on and off. compressors wont kick on if its losing pressure so it seems the leak is getting worse than he thought.
so after $500+ in parts and labor, the condensor core is a radiator like thing that my dad says might need special sealant and oil or something in there (didnt understand what he told me) and i find out its under the fucking dash.
so i am asking to see if swapping out a core is do-able DIY. if not, i will at least be taking the dash off myself to get to it (pretty sure i have toremove the dash unless its accessible under teh glove box or something). and that might save some labor since they'll just have to swap the cores and ill do th rest, saving me labor money.
if i do forego this procedure, i will need to know details on pulling the dash (im sure i can do it) but i will specifically need instructions on properly disconnecting and reconnecting the passenger side air bag. i do not want to make it go bad or blow up on me when i reconnect it.
thanx

Dan,
You will not have to pull the dash to remove the evaporator. I had to remove the evaporator from Garrett's S14 in order to remove his wiring harness through the firewall. You will need to remove the glove box first. Unbolt the blower motor and the evaporator after that. You will need good manual dexterity to get to some of the bolts and also a few long extensions will help.
Good luck,

thanx. i dunno if i would be replacing just some of it or the whole thing but would u know if there is any needed sealant/seals/oiling etc at all.
i drove around tonight and it stays on so im thinking that since it was just put together it needed to cut on and off a for a while to get back in its usual or something. but it hasnt been cutting on and off at all. i will drive it tomorrow in the day again since perhaps the heat might be doing it cuz tonight it was cooler out dunno if that would have anything to do with it.
thanx though. for now im fine which is a relief.

Dan,
The only "seals" you have to worry about are the rubber o-rings that go on the high and low pressure lines where they enter into the firewall. On the other side of the firewall under the dash is where the evaporator is. I would install new o-rings while you are in there. These can be purchased through Nissan or through auto parts stores in various sizes.
The only oil in the system is the mineral oil that lubricates the A/C compressor and you should not need to add any at all if you are simply replacing the evaporator.
Keep in mind that *any* time you open the A/C system to the atmosphere, such as when replacing a compressor, a line, or the evaporator, etc..., you will need to install a new drier/receiver. This the aluminum cannister located right next to the battery. Did they replace the drier when they fixed your A/C? If not, then there will be moisture trapped in the system, which makes the A/C not as cold as it should be.
Good luck figuring out your problem.

just wanted to close this "case" so to speak
yes i know u have to replace condensor/drier canister. they did so. they replaced 2 lines they said were leaking tho i can only find one that looks new. the L pressure line that has the big bulge that connects to the compressor.
the a/c works perfectly so am in no troubles at this moment.
thank you jay for the info.
oh and my new drier is brand new obviously it came shiny/polished
so if u get the new one for garrett's you might not have to do it. (but no it doesnt compare to stage 2 its only like stage 1 shine)
