K2500. Not sure if this the problem but on the climate control A/C button it doesn't light. So the compressor to HVAC doesn't turn on. Only blows hot air. Not sure what I can check or is it something else. Just need advice.

Good afternoon,

Do you have gauges to check the pressures on the high and low sides?

Did you check all the fuses for power on both sides?

I already checked the gauges also tried to add Freon just wanting to let you know. At first it only was blowing below but corrected that. As for the gauges to check the pressure I don't have one personally yet.

You checked the gauges but you don't have gauges to check?

Please explain? What were the pressures?

Did you check for power at the fuses with a test light?

Can you give me numbers on the gauges? I need this information to help you.
