I recently replaced both air shocks for the rear suspension. The repair went well and the bags filled with air no problem. Since the repair the compressor keeps filling the bags until they are full and then shuts off however, when i get out of the car the air suspension isn't releasing the air from the bags as it should be. Currently my air bags are fuller than they should be and my air suspension warning light keeps coming on. Any ideas on what may be wrong and how to fix it?
