Is the ECU connector under the passenger kick panel? I am trying to find exact location of the connector

 

Yes. The connectors are plugged into the bottom of the ECU.

 

Just checked; Results:

1) Unplugged the pressure switch and ground terminal 2 in the free wire harness connector. (Red and Blue). A/C kicked in and blow cold air when the engine and a/c is turned on

2) Unplugged the ECU connector and Checked voltage in A17. Did not show any voltage when the key is turned to II position. (By the way just want to be sure - a17 connector has two terminals - right? I connected the red probe of the multimeter to one and black to the other; Not sure if I need to swap and test again)

^Try this test again.

 

Tried it. Shorted the 2P plug terminals of the pressure switch with a jumper wire. NO; It did NOT engage the clutch; No cold air

 

Look at the circuit diagram in post #2. Your results are suggesting that the Blu/Wht wire running between the pressure switch to just below the condenser fan relay is broken. Try to trace wire to locate the break.

 

Just to clarify : Ideally when there is no fault, When I shorted the 2P plug terminals of the pressure switch with a jumper wire, this should have kicked the A/c Clutch? Right?

Any suggestions on how to trace this wire? is this a loose wire running in the engine compartment?

 

The A/C should have blown cold just like when you grounded terminal 2 of the unplugged pressure switch connector.

The problem could be a broken Blu/Wht wire or a bad hood fuse box. Start by checking for lack of continuity on the Blu/Wht wire between terminal 1 of the pressure switch connector and connector C214, which is plugged into connector C355 (see diagram).

 

Ok; Thanks; I will check the continuity. In the meanwhile how do I check/test the bad hood fuse box you have indicated?

Many thanks again for your help

 

That's a separate Blu/Wt-Blu/Wht wire continuity test from C355 to C905 (C353) on the underside of the hood fuse box.
