Hey guys, I have been having some problems with my 1992 LS-400's A/C. A few days ago, the check engine light came on. Within a day the A/C went out on my wife (boy was she hot, literally and physically).
My local mechanic hooked it up to a vacuum line, but could not find the leak. He put dye in system to help him find the leak the next time it happened. I picked the car up on Saturday and realized it was not blowing as cold of air as it had in the past. I drove for while and it began to blow warm air. Per the mechanic, he still could not find a leak, but said it could be a problem with A/C Control Unit or the fact the A/C rubber hose is deteriorating on the inside and is causing a blockage in the system.
I'm hoping maybe someone has some ideas or can let me know if the older models had problems with hose deterioration.
Thanks
