I have been trouble shooting my 2004 Jetta AC because it does not blow very cold. Here is the information I have so far.
-Had a bad fan control module and bad large fan so replaced the large fan and the fan control module so both fans working normally
-Clutch engages when the AC switch is on
-Low pressure side 100 PSI when the AC is off
-When the AC switch is turned on pressure drops quickly to around 40 then drifts backs up to 60 where is stabilizes
-When the AC switch is cycled the temperature of air drops consistent with the above statement
Thoughts? Thank you.
