2002 civic ex,automatic.1.7L vtec. 4 door.
A/C blow air but no cold.got a bottle at walmart and charged the ac,still no cold air.inside car a/c button/switch turns on.engine and a/c fans run ok.compressor clutch does not turns.tested clutch relay and is good. tested No2 on relay fuse box socket terminal and it has voltage.jump wire number 1 and 2 and clutch does click...any idea?
one thing got me thinking and is that i charged the a/c to 45psi and next day it was 35psi.i don not see any leak on the system.is it easy to see any leak bu just looking?unless i need to remove the compressor to look for leak?.....thanks for any help

 

If you suspect a leak, take it to a shop and have them check it.

Does the clutch on the compressor engage, or does it only click?

 

Connect the No. 1 and No. 2 terminals of the compressor clutch relay 4P socket with a jumper wire.

COMPRESSOR CLUTCH RELAY 4P SOCKET



Does the compressor clutch click ?

YES - Go to step 6.

NO - Go to step 14.

Disconnect the jumper wire.
Turn the ignition switch ON (II).
Measure the voltage between the No. 3 terminal of the compressor clutch relay 4P socket and body ground.

Is there battery voltage?

YES - Go to step 9.

NO - Repair open in the wire between the No. 14 fuse in the under-dash fuse/relay box and the compressor clutch relay.

thanks" IT wasn't me" for answering..

"This is what i did...and the compressor did click..did not engage at all...this test is done with car engine off"

 

How would you know if the clutch actually engaged unless the engine was running?

 

tanks....
I just following the manual,it show that to test the compressor the terminal 1 and 2 jump is with car off .
however i think your point make sense.i am going to jump terminal 1 an 2 and see what may be.

 

So if you test terminals 1 and 2 and the clutch does NOT click or engage with the car on what would the fuse box be the problem?

 

Pfft! You have a manual, and you can't figure this out?!


You should be able to sort this out on your own. Follow the procedures, rule out the possibilities, find the culprit, fix it.

 

thanks guys...i have the honda civic computer,search-able 2001-2005.3,4,5 door manual.i did all the testing ,so far can't find the problem.going to go over again and see

delsol.......testes fuse box and all good
