Is it still saying "a/c low" or any other a/c warning on the driver info center? Caddy's wont let the compressor come on til the codes have been cleared through the on-board system. To enter self diagnostics
Key on, press "warmer" and "off" at the same time, hold down until info center changes to diagnostic. Then press fan low until "ACM" is displayed. Then fan high until "ACM codes" is displayed. Then fan low until "clear ACM codes" is displayed. Then fan high to clear the codes "ACM codes cleared " will display. Turn key off.
