03 signature ac ????? driving me crazy...

[krfworcester@aol.com]

hello i have a 03 tc signature... when i put the AC on auto it seems to blow cold at when the cars at a stop but when i give it gas it seems to get warm.. i'm not sure about my troubleshooting because it does blow cold while driving at times too... it seems to have a decent charge being it does cool the car down just not great...... blower motor runs perfect and i never change the temp from 60 so don't think its a blender issue which ive seen before... also AC seems to run better when i turn on both climate controls in the front... any ideas???
thanks.. Keith

Have you had the system actually pressure tested?

 

[krfworcester@aol.com]

no i havent pressure tested the system i did add some freon.. it seemed pretty normal holding a charge... i have it about 5 notches above the charged area on fill valve.... ive always put my own freon in the towncars... do you know the exact amount of pressure its suppost to be at.. high and low side.. i'll try to get someone to check it..

Could be a vacuum loss?

Does it blow colder at idle but not so much when 'driving'?

How 'bout the cooling fan? Does it seem 'normal'?

yes it seems to blow very nice when at idle but when I'm driving at the air isn't as cold

I think there's a service bulletin for changing some orface in the AC line.. I had an 03 TC and was a member of Lincolns Online. Check there in the Town Car area, they may have a sticky to this problem.


Good Luck
