Re: AC Problem

["Harold McElraft" <hmcelraft@xxxx>]

What is the blower speed when this happens? If on speed one or two 
it is probably a connection to the clutch or, the blower motor is 
drawing too much current away from the clutch. Blower speeds one and 
two run on the clutch circuit. Disconnect and reconnect the clutch 
connections in the engine compartment - there are two right there by 
the compressor that often get contaminated. Also check the 
connections on the accumulator (just take them off and reattach a 
couple of times to clear a connection) If that doesn't work try 
blower speed three for a few days and see what happens. Blower 
speeds three and four run on a circuit separate of the clutch. If 
that seems to solve your problem I would say you should take out the 
blower motor and oil the felt for the bottom motor bushing. You can 
see it through the vent hole. It is probably dried out - most blower 
motors have new life after getting a good dose of oil on the felt 
(20w) and draw fewer amps. I do mine every several years when I hear 
it start to rumble or "knock" some.

great except for one annoying problem. After the AC has been running 
a while, say 30 to 45 minutes, it will begin to blow warm air. If I 
cut the AC off and then back on, it will begin to blow cold air 
again. Sometimes I have to do this several times in a row to fix the 
problem. This happens on either the Normal or Max switch setting. 
Any thoughts/suggestions?
