Hey everyone,
I searched the archives and found little help on this.
I charged the system (converted to 134-A) in my '70 LeBaron last night; but,
I had to run a 'hot' wire to the compressor to get it to run. It has the
Auto Temp (not the Auto Temp 2 system...please note) HVAC system. System
could use a partial can of refrigerant yet; but w/in opperating pressure.
What I'ld like to know is if there is something commonly malfunctioning on
this system to give me a base starting point in diagnosing the problem.
What I have already checked:
1. 20A fuse...power both sides (heater A/C fuse) (used test light)
2. No power to compressor (used test light)
3. No power present at the Low Pressure cut-off switch (used test light)
4 Vacuum lines all hooked up
I used a test light to check for power; but, I didn't have my Multimeter to
check how much power was present or the resistances of the switches.
I have located the Master Switch and Compressor Switch under the right side
of the dash. I didn't test these due to it being midnight, last night.
I have great hopes in working on the A/C tonight. I will have my multimeter
and vacuum gage/pump to better diagnos the system.
Out of curiosity...if I jump the Low Pressure Switch, Compressor Switch, and
Master Switch will the A/C compressor run/engage regardless???
Please help as you can. I'ld really like the A/C to work on the Chattanooga
trip in a couple weeks.
Thanks!
