  1. 1990 Coupe dies....

    I just recalled that I have an old combination OBD-I/OBD-II scan tool somewhere in my archives. I havent used it since I redid some 90s Lebaron Convertibles years ago. Arent the Reattas capable of being OBD-I scanned? Isnt the diagnostic port somewhere in the center console tower? My scan tool is an AutXray brand. Hpefully I can scan it so I can get this Coupe ready for winter duty so I can store the Convertible for the winter.

    When operating temperature reached on the gauge its right at the middle bar. The only problem I see with the IPC is the codes not being displayed completely where the mileage odometer is. Its like the letter and numerical symbols are missing "parts" and are incomplete. Everything else is fine with the disply. When in diagnostics it cycles though codes but some arent legible. I havent tried disconnecting the MAF yet so need to do that and other suggestions. Thanks.
  3. 1990 AC oriface tube question....

    Ive been incapacitated with an injured knee and one of the other convertibles and havent gotten back to the Coupe.
  4. 1990 Coupe dies....

    I had the symptoms of a bad crank sensor with the engine starting and when it reached operating temperature it would stall. I went ahead and checked fuel pressure (41lbs) and it held dropping to 35lbs with engine turned off. I checked codes and it seems there is a problem with the display that doesn't allow the letters and numbers to display entirely making it difficult to correctly read the codes. I proceeded by swapping out the Crank Sensor. Started engine and upon reaching operating temperature it stalled as before. I had left the Fuel Pressure Gauge attached and it displayed the original (KOEO) 41lbs after the stall. The Coils are new also. Can I rule out the oil pressure switch killing the fuel pump because of the 41lbs of fuel pressure displayed after the stall???? The faulty code display is making this into a mystery.
  5. 1990 AC oriface tube question....

    As I posted previously it appears the tube going to the evaporator has an ever-so-slight downward bend to it. Its enough to stop the new orifice tube and leave the long screen end with about 1/2in sticking out. Possibly the PO had yarned on it for some reason or other. The fitting and tube surface showed no distress marks except for that slight downward curve. Maybe the fact its bent has something to do with the fact no old orifice tube being present when I separated the fitting? Someone had obviously been into it. Going to do the evaporator flush suggested next. Thanks to 89Red and all for hanging in there!!!!
  6. 1990 AC oriface tube question....

    89Red....your pic of the 1990 evaporator (ROCKAUTO) is what my evaporator plumbimg looks like. As the 1990 FSM states "...the short screen end of the orifice tube inserts towards the evaporator ..." So your original answer is the correct one for a 1990 system! Short screen end always towards the evaporator and long screen end always towards the condenser for 1990 systems. I wonder why they needed to switch it up like that?
  7. 1990 AC oriface tube question....

    89Red...I believe you had it right the first time if my 1990 FSM is correct. It illustrates on page 1B-4 that for orifice tube replacement "install with shorter screen end toward evaporator and use new o-ring seals"
  8. 1990 AC oriface tube question....

    The aluminum line going thru the firewall to the evaporator appears to have an ever-so-slight curve and only allows the new orifice tube to go in to where about a half an inch remains out of the line. It seems to be seated as far as the orifice tubes o-ring is concerned. I don't see how it can migrate any further. New O-rings are being installed as I work my way towards the ACCUMULATOR. I think I'm resigned to having to pull the radiator to access the back of the compressor to remove the 15mm bolt holding the hoses to it.
  9. Brake line

  10. 1990 AC oriface tube question....

    Yes...I used a flashlight and theres nothing in the line. I will try and align it correctly and get it to to seat. I sure need to pick up the pace or I will be shoveling snow...but I'll have AC... Next is getting to that 15mm bolt holding the hoses on the compressor that go to the accumulator....any way to get to it without radiator removal?
  11. 1990 AC oriface tube question....

    My initial attempt to insert the orifice tube had it stopping with about a half inch of the long end left sticking out of the line. I didnt force it. Maybe it needs to be twisted slightly to get a little further past the dimples? I'm replacing green o-rings as I go and using silicon paste.
  12. I finally got started on the 90 convertible AC problems starting with the orifice tube replacement. Got the lines opened and to my surprise...NO ORIFICE TUBE! Is it possible to run the AC system without an orifice tube? I'm sure I opened the correct line. The one at the top of the firewall...smaller of the two and has the dimples a few inches back from the end. Also, does the short end of the orifice tube go towards the evaporator or does the long end?

    Thank you, Barney.
  14. 1990 AC system

    The ac system has been converted to R134a by PO. Was performing fine for a few seasons before compressor manifold tube cracked. I'm wondering about how many cans of R134a refrigerant it will require to recharge after I vacuum the system.?
  15. I'm redoing the AC system on my 1990 Coupe. The AC system was converted over to R134a refridgerant by the PO and worked fine for a couple of seasons before a cracked pipe at the hose coming off the compressor happened. I'm wondering what the correct orifice needed if different from the original R-12 tube. The difference of the different refridgerants at the molecular level being considered.
