Default xc o2 sensor and heating issue

I have a 2001 xc with 110K. I took it to the dealer due to the ck eng lite coming on. Dealer said an o2 sensor was causing the prob. I replaced the front o2 sensor then disconnected the battery for 2 minutes. Now the heater controls, front seat heat and shift indicator light are not working..50 miles later the eng lite is on again..please help, Rich.

You might have to rest the computers lock and unlock with the key and remote.
Also unhooking the battery WILL NOT CLEAR THE CODES IN THE COMPUTER.

Lock the door with the key like if you were leaving the car somewhere. Do it with the remote as well.

Tech, I moved this from New Members Area. I was not sure if the car was XC70 or XC90.
