Replacing the AC evaporator is a job best left to a service shop. It will involve recovering the refrigerant, cleaning the system and ports, checking sensors, checking the system for leaks and recharging the system.

1998 DeVille: what happens if I put 10w-40 oil in a 1998 cadilla...


I believe that 10w30 is recommended for the vehicle, but 10w-40 is a good substitute if 10w30 is not available.

Probably nothing bad will happen, but if the Driver Information System shows low oil pressure, revert back to the recommended viscosity.

My antennae won't retract and makes a whirring noise like it is struggling to go down(93 Cadilla Sedan DeVille)


There are plastic gears in the power antenna motor that strip out over time and when a large load is placed on them. The motor will need to be replaced or you might be able to take it apart and replace just the gears.
