A/C hiss noise, 96 Gr. Caravan
When the AC is on in my 96 GC (3.3L) I sometimes here a hssing noise coming
from the front left dash area. It lasts for about 10 seconds or so and then stops. It is especially noticable when the A/C is on and the ignition is turned off. A/C cooling performance seems fine. Any ideas? |

My experiences show that when the A/C makes internal hissing noises while it is running, this is a sign of low coolant. Mine has had a slow leak that my mechanic has been trying to identify. The system doesn't make any hissing noises when it's fully charged, but the hissing starts before I can tell any loss in cooling performance. HTH -Scott -- Scott Ehardt http://www.scehardt.com |
