It has been over 100 deg F all week here and I really need the air conditioning working on my Tracker. The pump I pulled out of the junkyard was no good. Surprise... Surprise. Hey, it happens sometimes. That's the gamble I take. So I ordered a new one, installed it, and it was broken. The manufacturer would not let me return for stupid reasons, so I decided to put the two A/C compressors together and make a good one.
