a/c compressor sys??

[itapol]

does the a/c have a relay or just the 10a fuse and 40a fan fuse? My system is fully charged but the air does not get cold....And I cannot not hear a click under the dash or at the compressor?

Check low side with guage is the green zone. Both fuses are not broken/separated..There is no click under speedo when go to ac mode via auto and lo temp...where is the clutch relay location and what part name and markings?
Thanks

To test a/c clutch relay and a/c clutch, remove rectangle cover over frost switch near expansion valve on evaporator box behind false firewall and with key on and a/c auto switch on, ground gray-black wire going to frost switch. Relay in dash behind speedo should click and engage a/c clutch whether you have freon or not. How do you know freon fully charged if compressor won't engage? How much pressure do you have in low side (blue hose on gage set)?
