[s-cars] HVAC 801 Error Code?

[Mark Strangways]

If the pressure can be read, then you can verify if in fact it is high or if
perhaps the switch has packed it in.
Generally, high compressor pressure results from the refrigerant not getting
cooled back down well enough, or not extracting enough heat from it on the
condenser side.

Have you cleaned the condenser ?
No obstructions or debris anywhere ?
What is the vapor line temperature at, is it real warm going into the
compressor ?
First I think you will need to check the pressure on the high side.
