95 accord no ground to AC controls

[89iroctpi5.7]

95 accord ex 5 speed 170000 miles 4cyl
I have 12 volts at comp and cond fan relays but no ground to relay coils
there is also no ground at low pressure switch
if i ground the low pres switch the fan will come on but the compressor will cut on only for a moment
if i jump the comprressor on at the relay it will run and pump normal
Do the controls get their ground from a computer or just from the fan control on dash?
I really need a wiring diaghram or some one familuar with this proble. ITS GETTING HOT HERE IN GA All help is apreciated

I bought one of these a few years ago and loaded it onto my laptop to take into the garage when I work on my 96 Accord it has saved me a lot of money.

well I a wiring diaghram and found out the compressor relay is grounded by the ecm and the condensor fan relay by the fan control module. The cond fan runs when the temp calls for it so I guss the fan module is ok but the ecm is not grounding the compressor relay.I thought maybe the ac button was not passing ground but it and the low pressur switch check ok Any body know what tells the ecu to ground the comp relay? Just dont want to by an ecu if thats not it

The ac tstat located in the evaporator housing was bad. Thanks to those who helped.
