Default HVAC problems anyone?

Just wondering if anyone has encountered the same problem as me. I'll turn onn A/C or the heater, and you can hear the fan blowing, but you can't really feel it out of the ducts. It does come out SLIGHTLY, but its definitley not as powerful as it should be.

See what happens when you turn the blower on high?

Also push the recirculate button and see what happens?

Look at what the outside temperature is displayed at?

On mine with the car sitting in the garage- underground- the outside temp is not correct for about 15 minute.

If none of the above changes cause the HVAC to change you probably need to take it in for service.

When I change the fan speeds, you can definitley hear it working harder. It does work on high as well, so I doubt its an electrical problem.

Outside temp is correct, just changed the ambient air temp sensor a few months ago.

Make sure the drain isn't plugged up.
