I've been out of town for the past few months on a work project. While gone, my wife took our 128i to the dealer for a blower motor wiring safety recall repair. Once I was back in town (~1 month after the repair), she and my son reported that the A/C was not blowing cold. I'm not sure how long it hasn't been blowing cold, as it's been cool enough here to not really need the A/C.
My question is - could replacing the wiring for the blower motor affect the A/C's ability to blow cold? I called the dealership and they told me that it is not possible and that they will change me $159.95 for a diag fee to tell me what's wrong. Before I push back and demand they diagnose for free, I would like the hive's opinion.
If you can't prove it stopped blowing cold air immediately after the recall repair, I don't think you have a leg to stand on.

I very much doubt they are related. I have the procedure for the recall repair around here somewhere (I wanted to see what was involved before I took mine in) and it's all done from the passenger footwell; there's nothing A/C related in there.
That said, my A/C has had a slow leak since I bought the car. I haven't spotted any leaks in the engine bay, and it's a really slow leak (holds vacuum fine when refilling, and the charge is usually good for a full spring-to-fall season). My indy thinks it's probably the evaporator, which is of course a huge repair. I just recharge mine every spring.
Thanks folks. I'll assume the events are unrelated and have my trusted indie diagnose the non-cold A/C
