"Accumulator jumper"??? If you are refering to the "old school" low pressure A/C switches that used to be located on the A/C accumulator, you will not find one on your 2001 Cadillac DeVille. They no longer use pressure "switches" they now use pressure "sensors". They work completely different from the older systems because they are computer controlled. Trying to "jump" them in an attempt to get the compressor clutch to engage can cause some serious computer system damage.

If your A/C compressor will not engage, you can check the system pressure with a conventional set of A/C gauges that have fittings for an R-134-A system. Other than that, you must have a scan tool that is capable of two-way communication with the HVAC and Engine Control (ECM or PCM) computers to properly diagnose the system.

Im getting low oil pressure reading on my 95 cadillac deville.. what should I be looking to replace?

always start at the least expensive item. ths would be the oil filter. if its a double wall one,switch to a single. if this doesnt work,then test the oil sending unit. alot of the older caddys do this,and as long as you dont hear lifters tapping,i wouldnt sweat it.
