Does anyone know where to get an heater box

My husband and I got a 1993 cadillac eldorado and it need a heater box. Does anyone know where to get one?

Removing compressor oil

Might have to much oil in system how can I take some out?

In my 93 Cadillac eldorado on the dash you can check the codes clear the codes but there are other options under a c p i c p s i r and one other where there is data override and input where can I go

Instagram wondering where can I go to understand what all the other options mean like I said in my question about the inputs the overrides I know what the clear codes mean and there's another one data. I was hoping someone out there could tell me where I could go and read up on what these mean and what I can do to either help diagnose my vehicle or fix issues. I've been a mechanic for over 25 years but I was mainly a front end mechanic did ball joints brakes rack and pinion things like that I never got into tune-ups or this type of stuff with the computer in the dash I would just plug in my OBD2 and there it was and then I fixed it I'm not familiar with OBD1 or Cadillacs any help would be greatly appreciated

1993 Eldorado 4.6 Northstar

A 93 Eldo was towed into my shop for starter (?) issues. I replaced the starter, car started twice but motor was making a grinding noise from the FRONT not the starter (so the starter wasnt stuck engaged) customer took the car home and I got it towed back the next day. Replaced the starter AGAIN, and the motor starts to turn over then clunks to a stop. Burned up a brand new starter without ever turning over the engine. I pulled the plugs thinking maybe hydro lock because he recently had a severe overheating issue so I suspected head gasket, plugs are burned but dry. I can turn motor over BACKWARDS no problem with a wrench but will not go forward. Any ideas? Im thinking timing belt jammed in gears?

My 93 Eldorado 4.9, will run for about 1 min. then jus dies. can anyone help ?
