my compressor will not come on and my a/c fan will not come to, a.c has right amount of oil and r134a. it is blowing hot air , what could be the problem

 

Check the condenser fan fuse in the under-hood fuse box (it's by the battery). If it is blown, neither the compressor or condenser fan will work.

 

fuse is not blown , there is a cooling fan relay and a/c compresor relay would tht not make them work

 

Yes, that was what I was going to have you check next.

There is also a relay over by the driver side headlight, mounted on the radiator support.

 

it is not labeled i think it is the one on the right but not sure

 

I'm not so sure either, actually... reason being that mine are actually just hanging there because the mount portion of the relays broke off.

 

What model year is it?

 

IF you have a 95 Civic:

1) Check 20A hood fuse 35 and 7.5A dash fuse 13

2) Check the A/C thermostat in the evaporator

3) Check the heater control panel

 

its a 95 civic vtec 1.6

 

Take the glove compartment out and locate the thermal control on top of the evaporator box. It has a 3 wire plug and a gray wire that's permanently attached. Unplug the plug and check the wires:

blue/white should have continuity to ground whenever the fan switch is on any setting other than off, and the A/C button pressed. If not, problem with the control panel.

yellow/black should have battery voltage whenever key is on.

yellow/white jump it to ground (or blue/white) with engine running, compressor should start.

If all these tests pass, thermal control is bad.
