my 1990 caddilac brougham is charged with 134A, think it may have been converted from r 12 though so make sure you know whats in it
hire someone hire someone
They only used the LT1 350 in Fleetwoods from 1994-96.
if its a 5.7 engine it is 18436572
40psi
r134a
could be numerous reasons, such a bad courtesy light switch on either of the 4 doors, a grounded courtesy switch wire, or possibly an entry module fault ( when you push in the lock button, and the interior lights come on ) . Good luck
change over to air shocks on rear end
It should be the stalk on the left side of the steering column behind the steering wheel
you cant unless you have a a/c recovery machine.gm Jim
OBD1...Fleetwood didn't use OBD2 until 1996, the last year (for true fleetwoods anyway)
cheapest way is to put a junk yard transmission in the car to rebuild it is about $2000 vs 600 for used transmission
it could be so many diffrent things google "error codes for a 1994 fleetwood brougham" it will send you to myweb.accesuss.com or .net..very usefull in tracking down the cause
