Hi
My Climate temperature control unit seems to not be getting any power all of a sudden. Nothing works on it anymore. AC button, Heater knob, seat warmer. The lights on the unit are not coming on and nothing comes on when you push the buttons or turn the knobs. I checked the fuses under the hood and the ones on the side of the dash on the drivers side and all are good.

The lighter and radio still work.

Any ideas?

Thank you

2001 XC70

If the battery power has been recently disconnected, then this is the cause. See more info here

Follow Howard's directions and disconnect/reconnect the battery to reboot the CCM. Good luck!

Thank you Howard. I disconnected the two positive battery cables and touched the two of them together with vice grips and inserted the ignition key and turned it to position II and left it that way while I bolted the two cables back to the post. The climate temperature control unit is working again.

P.S, Love your website as well. Very informative. Bookmarked [happy]
