Hello,
Thank you for your feedback. So I charged the system by adding a switch at the anti diesel relay. At that time the system recovered, vacuumed and then with the vehicle back up a running charged with R-12. The system was performing well. As I type this response this vehicle has a different wiring harness or option’s based upon what I’m looking at in the chassis manual picture. Instead of the tan wire coming from the control switch to the thermal switch on the evaporator housing. In conclusion the light blue wire that is at my thermal switch came from the blocking relay. Going back over this issue is quite time consuming and educational at the same time. It turns to be the blocking relay was bad. Thank you very much for your assistance with this issue. The picture wasn’t the greatest but it does show the difference in wiring identity.
