I bought my 83 deville for 2500 the engine and everything else is in good shape i went to a mechanic who said it should last a long time but the power locks do not work and the speedometer and what tells how many miles you have gone doesn't work. Does anybody have an idea what i can do to fix these problems.
I would start by checkingyourspeedometer cable to see if it is working properly. As far as the locks, I would start with a test light to see if you are gettingpower to the switch, etc.
