Hi all:
My wife's car is a 95 2+2 convertible with the AJ16 motor. Tonight as we came up the driveway we heard this light hum from an electrical motor working. At first I thought it was an auxilary fan working to cool the car as she had just arrived but it kept working. After 5 minutes or so I popped the hood and found the air pump still running. I unplugged the pump, it stopped, then pugged it back in, it started back up. After another 15 minutes while I search the forums to ascertain what it was I went out and unplugged it for good as I don't want it to deplete the battery.![Icon Emm](https://www.jaguarforums.com/forum/images/smilies/icon_emm.gif)
Is there a thermo switch that controlls this pump thats gone bad?![Icon Beerchug](https://www.jaguarforums.com/forum/images/smilies/icon_beerchug.gif)
Thanks all

The Electrolux air pump is operated by the ECM for a short period 2 times during cold start. It should not operate after that. The power relay for the air pump might be faulty keeping the pump running. There was a newer pump and fuse upgrade (25 amp to 30 amp) and a TSB for your car. The system is the same as the X300.
