A/C does not turn on?

Hi,

This could be the result of a few different things. I attached the wiring schematic for the circuit below so that you have a reference.

First, make sure there is power to and from the relevant fuses. I highlighted them in pic 1. If they are good, switch the relays with different ones in the box having the same part numbers. If there aren't any that are the same, here are links that explain how to test a relay and fuses:

If all checks good, take a look at this link to see if anything helps:

In most cases, if there is power to the system and it doesn't work, it is caused by low refrigerant in the system.

Here is a link that explains how to add freon to the system:

Let me know what you find or if you have questions.

Take care,

See pics below. Note: Pic 3 is the under-hood fuse box. I highlighted the relays and fuses to check.
