A/C not blowing cold anymore

its weird that it quit after replacing the battery.

Try:
desconnecting negative battery cable and wait 2min or so....
re-connect negative cable. start the car, check the AC

Try #2
Check AC Fuse [not sure where's located]

already checked fuses. i shall try disconnecting negative cable. i cannot believe this happened either. it just all got replaced back in january after we got the front in tboned. whole ac was destroyed

The a/c light come on at all? Ac compressor turning?

so the AC compressor was replaced before.

The reason why I said disconnect the battery and connect it again is because maybe the computer thinks the car is still running on low voltage.
by disconnecting the battery it will reset the computer and it will get a fresh start

back then [small story]
We have a 2007 ford taurus and the alternator was not charging the battery, the AC quit working because the alternator was not making enough amps to run the AC and other electrical functions.

do you think the AC compressor might still be under warranty?

My wife also has an 08 versa sedan and last fall the AC went. First there was hole in the hose and it drained all the fluid. Then 2 months later the compressor failed.

weeeeeeeeeeeeee

Check if the AC compressor get engaged if YES : the compressor may have problem or the gas is low pressure
No: harness problem or IPDM built in relay problem

with or without an accident, refrigerant could leak any where.
my evaporator was leaking. it was found after mechanic put leak detecting dye into the system. after two treatments of stop leak, so far so good. first stop leak lasted about 6 weeks. second treatment still working since mid July. if it leaks and stops again this year, wont get it fixed til next spring...or trade it when its paid for But the heat in TX lasts a lot longer than here! hope ya get fixed up soon

if there is low gas pressure is there any chance to make the compressor clutch not engaging??

^Yes that's exactly what happened to me, when the pressure gets too low, system doesn't start, and clutch doesn't engage.
My pressure loss is very slow, so i lost cold air first but the clutch still engaged for a few days, then eventually clutch stopped engaging when pressure was even lower.

ok this is really help me thank you my friend i will try to charge gas and check if it will solve the problem
because a few days ago there was poor cooling

awesome:woot:

The problem solved Thank you I found a leak from O ring
thank you again

My 07 versa . ac has not blown cold air.fan is blowing air on #4 only #1 2 #3 have very little air coming out.

Only one fan speed working sounds like a failed blower motor resistor.
