civc a/c problem

hey any help would secure your place in heaven.

98 honda civic

a/c blows cold when it is cool outside

when it is hot the a/c stops working

i have heard that the a/c switch on the dash could cause the problem, any
other ideas?

 

The most likely cause is low refrigerant, caused by a leak. The air coming
out of the vents should be 40ºF-45ºF on a hot day, max air setting, doors
and windows open. You may be able to restore performance with a recharge
kit from an auto parts store, but the system really needs professional
attention. Lots of these guys are dishonest or incompetent, and will give
you a big bill and your vehicle back, without all the leaks fixed. Ask
around for who has the best reputation locally.

thanks, earle,

i should have included this, the r-134 is full. no leaks

when i say it stops working i mean the compressor clutch disengages

thanks

Your AC won't work right if the coolant reservoir isn't full enough (air
in cooling system). . The engine doesn't generate the right signal to
the AC if it's sensors aren't immersed / reading correct temps.
Top up the reservoir (to MAX) three days in a row and see if it's
'using' coolant (displacing air, actually).

P.S. Have you changed the Cabin Filter lately?

curly, you are rockin'


i think this might be on the right track! the coolant was low.

i had the a/c problem a few weeks ago, i had low coolant at that time
too. i filled it up and the a/c problem went away, i didn't put the two
together though.


the civic has a cabin filter?

thanks.
