A/C question

I hope the mods will be okay with me posting here, lots more traffic on the p/u forum. I finally got the a/c working on my '72 burb, but the rear unit is not working. I replaced the relay for the rear unit but the blower still will not kick on. What's the next step? The resistor? Expansion valve?

Re: A/C question

The blower motor could be shot. Check to see if its getting power.

I ran a jumper wire and the fan motor works.
