Can you tell the difference between a HR6 and a DA6 compressor by looking at them if you cant see any part numbers? I bought my Fiero used, it has r134 fittings, but I cant tell if the compressor is HR6. It has a harrison label on it and looks pretty new, but who knows. Is there anything else visible on the compressor that would help me determine which model it is? The car is a 1986 GT and I understand that they came with the DA6. It looks like there was a r134 conversion, but I do not know if the compressor was changed out. DA6 will not work with R134 correct?

They look identical

86 would have come with a DA6, they're not recommended because they're not as durable (and at this point, REALLY not recommended due to age).
New compressors have come way down in price in the last several years, that's the way to go, even if you have an 88 the front seal and body seals are 30 years old now.
If the car appears to have a newer compressor, if it's painted black that's usually a good indicator it's a reman, if it has o-rings on the hose block instead of flat spots for sealing washers, also an indicator of an older reman or used compressor.

It is black. All I can make out on the tag is that it is a Harrison. What are the repercussions of putting r134 in a DA6? I want to convert to r134 anyway, so if it is a DA6 and it kills it there is really no harm done as I would have to replace the compressor anyway right?

I should also state that the fittings were previously converted to R134 but I dont know what the previous owner did.

Potential issue is the new compressor likely fails, throwing fine bits of rubber and metal all throughout the system, possibly clogging passages in the condenser, meaning you have to start over, with pieces of the old compressor possibly coming loose in the system killing the new compressor. You also then have to tear the whole thing apart again, and replace the accumulator again, clean out and replace the oil...

I did see that the compressor is stamped 469 but I cannot find any information about it anywhere. Anyone know where to find the compressor specs based on this number?

No, 1135026 is a V5 compressor, used on 86-88 Fiero 4 cylinders, much smaller than the DA6/HR6.

So I went ahead and bought a hr6 compressor, accumulator and orifice tube. The compressor is brand new, not a reman. Do I have to remove "switches" from the back of the old compressor and move them to the new one? Also, is there a adjustment required on the switch that connects to the accumulator? I heard something about backing the screw out between 1/8 and 1/4 turn. Should I use Ester oil since the lines originally had mineral oil? Any other advise for the conversion would be appreciated.
