I just pulled the codes from my A/C (Worked good last year, put a can in this year and it's not working great...) and the display flashed code: 155... Could anyone tell me what the code means?
 
Here's how to abtain the correct A/C codes:

FLOOR + OFF at the same time on the EATC, then hit AUTOMATIC. about 60 seconds later started flashing "155" over and over again. Ill go out and do it again =)
 
I just pulled it again, flashing "155" from the EATC. I reset it using DEFROST and it displays all charectors from the display after another test. I also found this:

Component Description:
107. ELECTRICAL SYSTEM:IGNITION:MODULE
Bulletin Number: 96269
Bulletin Date: Dec 1996
Vehicle: 1,997 Lincoln Mark VIII

Summary:
EATC - INVALID DIAGNOSTIC CODES U1235 AND 155 MAY BE DISPLAYED DURING SELF TEST - VEHICLES BUILT THROUGH 7/1/97 - MESSAGE CENTER - INVALID CHECK TRACTION CONTROL AND/OR INVALID DIAGNOSTIC CODES U1009, U1027 AND/OR U1059 MAY BE DISPLAYED DUR ( NHTSA ITEM NUMBER - 50995 )

The RPM's fluctuate and the compressor kicks on and off, so I'm low on 134a... I'll fill it up.

How many Ounces is the system designed to hold?
 
Are you SURE that the compressor clutch air gap is between .013-.033 " ? If clutch is worn, you may have to remove a shim. I had to in my '97!
 
I guess YOU don't own a CD manual either, eh? Hold on, lemme see if I can can find the info again.... altho if you search in the A/C forum, you should be able to find it.....I KNOW it's there.....
