Is there a straight forward way to check the compressor relay? Saw this reference online "If the relay sticks [ed: closed] when the ignition switch is turned to LOCK (0), and the compressor was running, it creates enough parasitic draw to discharge the battery."
If you had to explain that to a non-technical person...how would I test the relay to see if that's also an issue? For example, I get cold air when AC is on and haven't had issues in the past with it.
Ok, Get a flash light and look at the a/c compressor ( bottom under the alternator close to radiator) Have someone turn the climate control off and on. You will see the very end if the compressor (black disc) start and stop when the a/c is turned off and on if it does then the relay is ok. If not then the relay is bad.
Well, I haven't checked A/C Compressor yet, but I took it to Goodyear and was told the alternator was failing 3 out of 10 times, especially while at idle state...something about it being way too high, more or less burning the battery up. They weren't sure this was causing the SUV to not start, but obviously I didn't want to spend another dollar there after replacing the alternator so I left without having anything else (i.e. electrical analysis) done.
Could it be related to the instrument cluster? Maybe the Starter or maybe I should check all the fuses? I haven't experienced the issue since changing the alternator at least, but I also disconnected the HFL. I should also point out there was an aftermarket flip down DVD player installed before I bought the car, but it wasn't working (beyond the embedded overhead light when door is open).
Basically, trying to figure out if the alternator could have been causing this or if I will eventually need to keep probing.
