Recently in shop. Replaced sensor, relay & blower motor. Did not fix it. Mechanic said 2 fuses for the AC should put out 12 volts currently only doing 1 volt. Problem started about 1 month ago taking longer for AC to come on. Then 2 weeks seldom comes on but works and cools fine until car is cut off. Then will not come back on again.
Why is my AC only running occasionally or not at all? on 2007 Nissan Murano

Have a MECHANIC check for proper voltage and ground at the compressor terminal connector with system on max. IF--'IF' present then most likely the clutch field coil is weak or deffective! Sometimes a simple tap, by a 'mechanic', on the clutch plate will activate the compressor clutch and it will work until switched off again. This is one possible cause of intermittent compressor operation, and may/should have been tested already! You can check to see if it has been. NOT for DIY testing!!!!!
