For the most part Ive been able to handle commuting with no AC, little sweaty after the drive but whatever. I was just curious How expensive it would be to make my AC unit blow ice cold?

My AC works but blows warm temperature air and gets warmer as car heats up.

Is this a DIY project or not?
Anyone done it?
More then $150 total?

Also I have a brand new electric fan, should I install this if I fix my ac maybe to reduce stress on car?

PS- I did search a bit but only found a few 2nd gen threads

 

u might just need to recharge your ac system from the sound of it

 

I had the same problem with my 85 GS a few years ago. I was lucky and had a friend of mine help me with it. He had the gauge set-up required to check it out as well as some R-12 refridgerant(sp?). What he did was pull a vacum on the a/c system and wait about 10 minutes to determine if it had a major leak. I was lucky in that the gauge indicated that it held the vacum meaning that the system was pretty well sealed. He than recharged the system with the R-12. It has been fine for the last several years. We think that since I store the car for 6 months out of the year the seals may have dried out during that time allowing for some minor leakage. Once I ran the system and got the oil recirculating the seals resealed. This may be your caes as well. The hard part is getting your hands on the R-12. It is expensive and you need a license to buy it. I think that you can rent the gauge set-up at some of the auto supply houses.

Good Luck!

 

I was actually having the same problem up until earlier today. I found out that there was a leak, so all my freon was gone, and I also needed to replace the compressor. Since i'm not doing it myself, it's costing about $1000 for parts, service, and whatever else... I think this is the second time this has happened with my SE...

 

well if u can buy the r-134a in your state it should cost less then $40 all u need is to let all the old freon out and put a adapter on the fitting adn then u can fill it with the new r134a

 

damn that sounds expensive.....crap.

the r12 is the refrigerant and that is what is most expensive?
i thought i could re-charge it myself but guess not.

Thanks guys

 

can u buy the new freon in cali? the r134a stuff?

 

no clue... but what would i need to "re-charge it"?

 

Its not as hard as it sounds, you can either disconect one of the lines and let it out into or I think there's like a way of containing that thing that I'm sure no one does. As far as recharging, all it basically is, there's a spot in one of the lines that has like a threaded part and with a one way valve in there. So basically you thread the hose part from the can to the line, and press the button on the can ... its fairly simple

 

its SUPER simple lol...im 15 and did it myself....converted from r12 to r134a

 

Best thing to do if you are not comfortable with retro-fitting your system is to take it to a competent repair shop.

This way the complete system is checked out. They will pull all of the old freon out along with any contaminants. Put a vacuum on it and determine if there are any leaks, then service the system.
Most shops that do the retro do it for around $200-$250 That should include the freon,needed fittings and the labor.
