A/C acting funny

[albarran9 10+ year member]

when i bought my car from my nighbor the ac didnt work. He fixed it for me befor i bought it from him supposedly and changed the compressor. it worked fine but that was in december when the cold ac wasnt needed. now it works but it would not get cold air coming out of it. i put in some new coolant stuff in it and some leak sealant. I think it might have a leak in there some where, but the sealant was supposed to show red dye where the leake was and i didnt see any red. it shoots out cold air now but what could of caused the ac to not shoot out cold air befor since there seemed to not be a leak? I'll have to wait and see if the sealant fixed any leaks it might have had. dose any one know what migh be wrong with my ac so i can try and fix it b for i go and and sped a bundle to get it fixed?

beats me...maybe a problem with the ac belt...or maybe it just needed some coolant

i just added coolant in december and tonight

if it was the beld shouldt it keep the coolant in? and it still gets power so the belt should be ok?

Yea, but even if you dont have a belt its still possible for the coolant to leak. If your ac isnt cold, there is only 3 possibilites.

1) broken compressor

2)leak

)Broken belt

Is it making alot of clicking and popping under the hood when the A/C is on, but sounds quiet when it's switched off? If that's the case, it's a faulty compressor.

I had a similar problem once, the AC would come on but it wasn't blowing cold air. I then realized that my cruise control wasn't working either, the fuse was blown. Check that and see if it solves you problem...

LOL!

Is anybody else in the HVAC field? Cause this is amusing....

The reason why you probably didn't see the leak is because it was probably in an area you can't see... :wink:

I hope you put the right refridgerant in....

Additional info:

It sounds like a leak to me, hopefully the sealant works for you, if not, don't try to fix it, you don't know what your doing. Take it to a shop.

X2 on the shop...some people get themselves into more expenses when they try to repair things on their own and end up making the problem worst
