Re: AC compressor failure?

[jtrealty@xxxx]

Check for continuaty at the low pressure switch located behind the 
front right wheel. If it doesn't have continuaty it is either bad or 
there is not enough pressure to trip it. Since you say the A/C worked 
for 2 weeks I am guessing that you had a leak and now there isn't 
enough freon in the system so the low pressure switch is keeping the 
compressor from running. Pressure isn't enough, you must have the 
proper pressure. A quick test would be a paper clip jumping the low 
pressure switch just to see if the compressor will run. DO NOT run the 
compressor any length of time like this because if the pressures in 
the system go below atmospheric you will pull air and contaminants 
into the system. You usually cannot just shoot a little freon in and 
fix the system, you really have to repair the leak that caused the 
system to be low in the first place! Any shop that doesn't leak test a 
low system is doing the customer a disservice in that they are just 
wasting freon, charging the customer for a temporary repair that just 
has to be done again, and polluting the environment by needleesly 
leaking R-12. My guess is you have a high side leak like the hose from 
the compressor to the condensor or a seal by the compressor or the "O" 
rings on the hose for the system to go flat so quickly.
