quick description of problem....system is charged, compressor clutch works, fan turns on but the problem is it blows warm on hot days and cold in the mornings...could it be a bad compressor?? i did reinstall the a/c system back into the car because the previous owner removed it....would replacing the compressor help??

any help would be appriciated!! thanks in advance H-Tech'rs!!!
oh one more thing...i took a condensor out of my buddies wreked EG so i have that availble to replace if it may be that...does the condensor have anything to do with cooling?....
oh car is a 92 EG with B18

The air mix cable/lever on the climate controls may need adjustment or replacement. Turn the temperature ****/switch all the way to cold, play with the air mix cable/lever a little, then turn on car and A/C, and see if it makes a difference.

Here is a picture, so you get the idea:

yeah that was my first thought too.

one thing you can check is the low side line (the larger diameter) after the a/c has been running for a moment. it should start to "sweat" if the system is working correctly. if it doesn't you can go from there and start figuring why it isn't working

MARDC5R

damn ya'll are fast!! thanks so much...i'll check the air mix on the climate comtrol....i did see "sweating" on the low side line...i'll double check that for sure...thanks again!!

I had a similar problem with my AC when i first installed it...... so i took to my friend took it to my frien that work on AC's and he hooked a vacuum pump to it and suck the air out to a create vacuum in the system, and with that is was fixed

MARDC5R

i had a friend vacuum the air out before we recharged it but he is a building a/c guy not a car a/c guy so maybe we didnt do it right?? that is somthing that i may look into also....thanks a bunch!!!

I am sure he knew what he was doing and sucked it down to the proper levels and for the right durration of time. Check the cable to the valve adjustment.

MARDC5R

ya tru that...i just wanted to keep that sugguestion in the bank...just in case...

im checking that cable valve adjustment asap!!..thanks again guys

MARDC5R

ok, guys im back...tried messing with the air/temp valve...no luck....here is another thing im noticing....when i am crusing at highway speed 50-60 my cars pull drops then gains, then drops, then gains....almost like im letting off of the gas and giving gas, letting off then giving etc.........i know thats the compressor kicking on and off....do ya'll think its a bad compressor??....
sorry for the many questions but im just trying to keep me and my son cool on the way home from work/daycare...thanks!!!!

Compressor is coming off and on like you mentioned. Could be because of a few reasons. I would first check the refrigerant level. Thats going to be the most common cause for it to cycle like that. If the level is fine, check for restrictions. Excessive high side pressure will cause the system to shut down as well. If thats not it then I would suspect either excessive clutch clearance on the compressor or a wiring issue (loose connection).

MARDC5R

wow...are you like waiting around for my a/c questions!!?? LOL! you have been such a big help....ok how do i check the "high side pressure" and excessive clutch clearance?
as for the wiring issue i could check my self visually i guess.......it feels like it wants to cool but its just that...its cool air..not cold.....the mornings are fine but this daytime texas heat makes her struggle in the afternoons...should i take it to take it to a specialist?? i just dont want to get my eyes poked out...i guess i could take it to a shop and just tell them to check my refrig levels??

thanks again Hybrid96EK!!!!

No. Was just still subscribed to the thread and happened to be here also. Well, chances are you don't have a set of gauges... so at this point I would reccomend taking it to a shop to have the system checked. Sounds like its very low on refrigerant, but without the car here I can't say for sure. Since you don't have the equipment to verify, a shop should have a look at it.

MARDC5R

ok, i seen some places around here with signs stating 19.95 a/c check...sounds good enough....well dont unsubscribe and thanks again man!!! if i could get this thing fixed i'll be so happy!!

You need to go get the pressures checked. You may have a clogged filter.

tigueremalo

what belt did u use for your ac???

Hybrid96EK

That would be nice, but there is no "filter" so to speak in that system.

When I overfilled mine it did that kick in and off thing like you described, so I literally had no power.

As for not blowing cold, just being a little under the minimum level of freon can cause that. Mine was just under it and it blew warm during the day. After vacuuming it out and putting the right amount in, it works well. Not freezing cold like I wish, but what can you expect with a 100hp motor lol

yeah thats what im thinking, i never really had it looked and recharged by a auto a/c specialist...i'm going next week so we'll see whats up!! I'm hoping for frezzing cold!!! lol

thanks again guys for all your help!!
i'll post the results

tigueremalo

All A/C systems have a filter inline to protect the compressor and condenser. Its about the thickness of a pencil and clogs very easily!!

Go back to school and get more education on the subject before you deem yourself an expert. Passing out bad advice isn't helping this guy any.

Dont believe I deemed myself an expert at any point. I may be wrong about a "filter" in all A/C systems, however, from what I have seen in most A/C systems that went bad was that a screen element that protects the compressor builds up with a metallic film that clogs the screen element and causes the system to build up with pressure. I dont do a/c, and obviously thats aparent. Just tryin to offer things to consider that I have seen lately.

ok great news.....got he a/c fixed...i had to much freon in my system and a squashed a/c line....im so happy!! now it blows nice and cold...not ice cold but cold enough to keep me from sweating in the Texas heat...thanks guys!!!!!!
