Hearing a low level noise from the dash when hvac is on. might describe the noise as a rumble but it is very faint and does not seem to vary with the fan speed other than with fan on high the noise is drowned out. Noise is heard best when vehicle is stopped and engine at idle. Jeep is still in warrantee so i will run it over to the local dealer next week but i would like to know if anyone else has seen similar issue.
About 13 k miles on the jeep.
