1994 Jetta help needed

dabunk on Wed April 29, 2009 1:42 PM User is offline

Year: 1994
Make: Jetta
Engine Size: 2.0

I just bought this VW for my wife. AC clutch engages but only gets lukewarm. Compressor is labeled for 134A and stricker under the hood says 134A. So I went to connect my gauges and the low side connector seems bigger than my gauge connector. My question is was the 94 model year designed for 134A or is this possibly a retrofit with different style connectors, or does VW use different connections? My experience is only on US AC systems through work. Thanks Dave

The VW Jeeta 2.0 was designed/built for r134a from July 1992. I'm not aware of VW using non-standard service valve couplings.

Thanks for the information. I just was out with the VW in the sun looking at it closer. It almost looks like a R12 fitting with an adapter screwed over it. I do not want to see if it loosens up, but I tried one of the 134A can taps as well and it does not fit. this will take some more looking into, shaking my head!!!

Try to post a picture of the line and fitting you are referring to. 94 was R134a..Hope this helps..

Those are standard R134a fittings, the one on the left is LOW and the one on the right is HIGH.. I never had a problem hooking to those VW's.. Could be bad couplers??

Well I checked my guages on my safari van and they set nice and tight. I will have to look closer at the VW and see if maybe they are damaged in some way. I will post back. Thanks for the help. Dave

OK got it finally. Got in there with a small micrometer and fitting is slightly oval. Got in there with a small clamp, wrapped it in rubber and made it round again. Works good now, only to find pressures are good. Think it is a blend door problem now as if I move the temp controller dial on the dash from the extreme cold position just slightly towards hot, it blows full hot. Thanks for the help. Dave
