Hey jack,
I used some of the recent info and I confirmed a couple things that I knew, one the evaporator is good, the compressor is good and working (and I am aware of the slow leak but a separate problem), blowing cold air.
I think what i found that is most significant, well two things, one the fan does in fact only work in the high position. Before I thought I heard some fan movement in low and med but when I actually go to the blower it is not turning at all.
The second thing is the test on that blower relay, which coincidentally seems to be called "AC blower hi". Of the 5 pins, 3 are expected and DO show voltage. The other two are expected to show zero and less than 15ohms resistance. [A thought occured to me as I reviewed this post. The troubleshooting procedures are having me check the wires BEFORE they entire the relay. Not sure why I would get any resistance on the input to the relay, if anything the relay should provide the resistance, shouldn't it? That would indicate that a component prior to the relay would serve as the resistor. - Just a thought]
It says replace if they don't. Both showed zero. Now, since one pin no longer shows resistance, in my own little head, resistance means that probably controlled one of the lower speeds and not the higher. So I have no idea if replacing that will do anything more than give me back the low and med speeds but who knows.
However, since it is cheap, I had ordered it earlier today. Ecklers thinks that it might be my initial hunch, that the blower just needs to be replaced. But I have not been able to talk to anyone at length yet on the phone.
The only question nobody has answered was whether there has ever been a case in which the blower still works but does not blow as it did when it was new. In short, do they get old and slow down or is this an "either it works or doesn't" situation.
Anyway, appreciate the help from you and all.
