2005 Buick Rendezvous AC Electrcial

I assume when you say no fans you are talking about inside the vehicle. If so then the what you were looking at as far as cooling fans are the fans that cool the engine that are mounted on the Radiator.

What you will need to look for as far as the fan inside the vehicle is a blower motor. Did you check the fuse block under the dash?

You can check the A/C Compressure by looking at it before you start it up so you know what it looks like. Then Have someone start the vehicle with the A/C Off to begin with while you what the compressure. Then have them turn the A/C on. You should see the very front of the compressure engage and start spinning. If you notice the front part is starting and stopping every 3 - 5 or so seconds you are probably low on freon.

Now the blower motor... look for a blower motor relay it is a square or rectangular box. There may be a regular fuse for it instead. There is also a blower motor resister that is located in the duct work under the passenger dash it looks like this....

I am better at some diagnostic with hands on than trying to explain. So, I have asked for some input from the other mods and techs.

Looks like there is another fuse block in the center console. Contains 2 fuses for the HVAC, one of them is for the control panel, it is 10 amp. Check that with atest light and get back, Oh and by the way, exactly which model is that?( CX, CXL, or Ultra) And does it have automatic a/c

Now need to remove the control panel from the dash and verify that there is power at the following wires-
A11 and A12 on the connector, if you have power there and it doesnt work, the control head may have failed. Check A10 to be sure it is a good ground too

Could save you some time and aggravation
