[DML] Re: Quick A/C pressure question...

When David says AC "running" he means at 2,000 RPM too, fan speed on 
high and ac mode switch on max. Both air fans in front should be 
running well also.

David's right - leave this sort of thing to the folks that know AC 
and have the right tools. In your area that should be easy.

BTW what is the problem?
