Was purchased in winter , tried ac now and no cold air coming out. Checked Freon level and was okay, fans come on but not as soon as you turn A/C on, but they come on sometime then they go off. Pulled codes 00819 high pressure sensor G65 signal too low, and 01317 instrument cluster control module j285 plz read DTC. Where is the pressure sensor located?

Hi,

The high-pressure switch is located behind the front bumper and mounted to the condenser. If you look at the pics below, they provide the directions specific to your vehicle for replacement. The front bumper cover will need to be removed to access it.

As far as the code related to the cluster module, that can be the cause as well. The remaining pictures are the diagnostics related to the code you provided.

The last two pics are the schematic for the computer data lines.

I hope this helps. Let me know.

Take care,

Joe
