I have a 2000 DTS. Today my mom was driving it and the a/c stopped working. When I got home I started it up and turned on the a/c and i hear some clicking and subtle thumping noises inside the dash but no air blows out when the switch is turned to a/c or heat. Also, I checked under the hood to see if the a/c compressor clutch had engaged but it was not turning. Now, I think my problem is gonna be a fuse, switch or relay if it isn't the blower motor itself. Can anyone point me in the right direction?

you are describing many different problems.


so first does the fan work at all

 

Thanks for reply. I know its been a while but I wanted to say that i fixed it. Turns out it was the blower motor. I know I mentioned in my previous thread that the ac compressor was not turning when it actually was. So I went under the dash and disconnected the blower motor, applied 12V at the pins and nothing. I replaced it for $52 new about a week after my first thread and its been working fine since.
