Removing the PC board to solder any cracks I can find. Got the procedure visualized from the archives and FAQ. Now I need pictures and a lot of luck. Dash is pulled apart. Have the radio in the back seat. Everything else in the front passenger floorboard except the screws which are duck taped to the center console. Jumping the low pressure switch no longer engages the compressor clutch. Have not been running the A/C this way, just wanted to get into a wait and see mode before I fixed a symptom of intermittent A/C vs. the root cause.
If I fry the board, oh well!! The job needs to get done as no A/C in this heatwave is causing my dry cleaning bills to eat into my IPD sway bar allowance!!
No computer shop here will touch it. I found a replacement vendor named Southwest Auto that has rebuilts for $175 plus my core. Beats the dealer by a country mile!!
Will post results.
