    I tried the Google search suggested and also looked on YouTube and found nothing on how to take the dash apart. I am getting an annoying buzzing noise from what i believe ti be the temperature sensor that is located to the left of the steering wheel, right behind a little vented area in the dash.

If I am not mistaken, doesn't it just go thru the plastic trim at the edge of the windshield? That piece just snaps into the dash cap. You should be able to get under one of the edges and pop it up and then work your way across. This should give you access to replace the sensor.

I need to change the temperature sensor on my buick lucern

You do not need to drain the system. Make sure engine is cool enough to work on, have new sensor ready, remove old sensor and quickly install new one. Just top up radiator fluid. No bleeding required.

2001 S60 T5 ambient temperature sensor problem

It's been a while since you asked but in the event you still have this issue - I would definitely start with testing the sensor to start and if found faulty, replace.

On my 2007 S60 T5 I experienced similarly erratic ambient temperature readings which effected my A/C operation.
While awaiting the arrival of the replacement sensor (~$15) I removed the door panels and treated the various wiring connectors to some contact cleaner and dielectric grease during reassmebly.. Despite a Volvo Service Bulletin highlighting potential problems with corroded wiring harnesses; in my case the connectors all looks clean and corrosion free - and after this exercise there was no improvement with the erractic ambient temperature readings.

Once the sensor arrived I was able to easily replace it. It took less than 15 min and required only a plastic pry bar and T15 Torex wrench. Testing the sensors with an DVM I found that the new/good sensor read 167K Ohms, while the old/faulty sensor was open with no resistance reading.

Thus on the basis of my personal experience I would recommend testing the sensor to start and if it is found to be the problem, replace. If it is not faulty then proceed with cleaning wiring harness connections.
