Yes, there's a relay, it's located towards the back of the passenger fender. It's the front most relay.

Assuming that all vehicle fuses are good, jumper the lead for the low pressure switch located on the drier and place the A/C switch to MAX. If the compressor engages, the problem is in the low pressure switch. The low pressure switch can be changed out without discharging the system because there is a schrader valve in the drier.
