I have a 96 S10 Blazer with 4 wheel drive 4.3 litre engine. The compressor has a leak between the back plate and the compressor itself. Is there a seel around there. I dont see one on the exploded view in Alldata. The only seal I see is the front seel behind the clutch the o rings where the hoses connect and an o ring for the high pressure cut off mounted in the back plate. I replace the o ring and the switch because I thought it was leaking by that o ring but the dye shows up all the way around the connection between the back plate and compresor. Any ideas?

If the compressor itself is leaking it may be time for a new compressor.
There is a seal on the case half but sometimes you can never get them to seal up.
Most parts places have a line of New or rebuilt compressor at a good price.
