I have a 2000 Accord 3.0L with an A/C not engaging . I checked all points .But have no power at relay line side ??? I do not have a blown fuse or bad relay ,The controls work as far as fans and blower fan.Can it be the Fan blower resistor or the thermal switch ? And how do I test the thermal switch ?

 

Have you checked the "freon" to see if you are low? I believe that can also cause the ac not to engage, when too high or too low. Probably just checking the obvious, but it's happened to me.

 

Like stated above is the freon level is to go and won't engage the clutch

 

yes all is good , I jumped clutch and the A/C blew cold

 

So you fixed it?

 

Can you explain to me here what you did? You jumped what exactly? Because it sounds to me like you bypassed some safeties.

 

I took a wire from the battery to the load side of the relay socket . That will check the continuity from relay socket to compressor . The problem is i have no voltage to the line side of the relay socket .Not the coil but the switched part of the relay . Line is hot (12VDC), load is compressor side .It kicked in . Fuses have been checked all is good., Relays are all good !
Ist here a hidden fuse someplace maybe?or an i looking at an open wire from fuse to relay ?

 

No not fixed yet ! Please check out reply maybe that can answer some of your questions you have for me ,and BTW thanks to all you guys for the help
