Air Conditioning Issue

Postby heathw » Fri Sep 13, 2019 6:02 am

I have a 91 pickup that I transplanted a diesel in. Lately my a/c is not cooling like it should. Here is what I have noticed:

The a/c clutch still engages, but doesn't bog the engine like usual. I used to here a click behind the glove box now and then,but not any more. The low side pressure is at 55psi when 85 degrees.

Has anyone ran into this before? Are there anything specific I can troubleshoot?
