Changed out battery on 2008 Impala. Connecting new battery and the air pump comes on and runs for a while then shuts off. I drove car about 20 miles thinking maybe computer has to reset. No luck.

With the key off, the pump motor starts to run for about 3 or 4 minutes then shuts off. Fifteen minutes later it start again. Any ideas?

I wonder if you have a confused HVAC soleniod. From what I have found with BING, this seems to be an issue with the Impala's on batery change, you need to denergize the electrical by swiping the battery cable over the post before hooking up. Seems to confuse them. You can pull the neg and swip it to deenergize the electrical system and see if it fixed the Soleniod.

Good luck.
