Default Help with A/C

At the end of last summer my A/C stopped working Won’t turn on no light. For a couple weeks before it was blowing less than cold air. My thought before the brutal Florida summer starts again is just to replace all the components because of the 24/7 usage that I get out of my AC here in Florida. My question is are all the parts available new for a 95 D21? If so what’s a good source for the parts?
Thanks

probably has a leak, the AC system is a sealed system and if the air was not getting as cold in the past and now the AC won't turn on at all it's probably low on freon. I wouldn't replace everything unless it's needed but the drier should be replaced anytime the system is opened.

I used rockauto when I replaced the drier, expansion valve and evaporator in my 93, no problems other than having to tweak the lines on the evaporator to line up.

NO, NO, NO !!!

Not necessary, and a ridiculous thought really, to replace all the components!!! I'm in Arizona, we use the AC all the time too, and you don't know HOT until you've had 122 °F !!!

A REAL AC shop can evacuate and measure the amount of R134a in your system, by weight; gauges can give an indication, but weighing the refrigerant is the real way to determine whether refrigerant has leaked out.

Understand: refrigerant is expected to leak out at a very slow rate through the compressor shaft seal, needed to lube that seal. Prior to vehicle designs that had the compressor turn on with the defroster setting, the owner's manuals recommended running the AC for a few minutes every few weeks in winter for that reason.

OK - here's my hands-on with AC on my '98 and 2004 Frontiers. I've had the '98 since 2004 and it needed a 12 oz. add of R134a a few years ago, has been fine since except for an unrelated pinhole in the high pressure line, which I fixed (now 225K on it). My 2004 Frontier AC was producing less cold, so that also got 12 oz. R134a last summer (100K), first time that AC was ever touched. Remember: I've got AC gauge set, vacuum pump, etc., so I'm pretty experienced in AC.

So I'm NOT saying just to get a can or two of R134a and adding that (but if you know what you're doing and add only PURE R134a to see if that restores operation I wouldn't yell at you), I'm saying take it to a shop, and evacuation/weigh/fill and add of UV dye should be under $125; and the UV dye should help with finding any future leak. WHATEVER you do, NEVER add any refrigerant containing leak sealer or leak stop, you'll ruin the entire AC system !!!

OK: here's common places for refrigerant to leak out:
1. compressor shaft seal
2. rubber AC lines (more likely the high pressure line) or the crimps of the metal parts to those lines
3. connections/fittings due to vibrations

or go to a shop, have the system discharged. then “rent” the vacuum pump and manifold gauge set from oriellys or auto zone and pull a good long vacuum and charge the system yourself with oil and the dyed 134. that will be a total cost of probably 30 bucks if you do it that way.

for an easy system test you can unplug the pressure switch on the drier and jump it with a paperclip. that will tell the system that the freon is full and should trigger the compressor if everything else is normal.

Last year, when 100 miles away from my own equipment, I did get the free loaner vacuum pump and R134a gauge set from the local Autozone and they were decent units.

So if you know what you're doing, know how to purge the lines, etc., then this is a decent option. Dye can be added directly, or as dye already in cans containing refrigerant - but make sure such cans do NOT contain any sealers, which can ruin your system !!!

Note that venting remaining refrigerant from your system is contrary to EPA regulations.

check to see if you lighter works. Mine shorted out due to rust and blew the fuse. that fuse powers the ac button.

Owner stated "For a couple weeks before it was blowing less than cold air.". That does not sound like an electrical wiring issue to the button to me.

id say the freon has seeped out. most common area besides the compressor shaft is the top 10mm fitting on the condenser.
