Need Advice Please.
My '88 124(Euro)300TD Turbo has these two (expensive) relays just behind the battery. My AC compressor turns itself off regularly while running, and the only way to reactivate it is to kill the ignition and restart the engine, sometimes more than once, before I get it cooling. What works more often is when I flick the ignition switch quickly off/on while running and before the engine shuts down. This does'nt feel right, but it works faster. Mechanic says the "Klima/Kickdown" relay needs replacing.
Right behind this is another relay which the mechanic says controls the Tach. This one's been acting up too. Sometimes my tach just goes dead resulting in the rpm's decrease while idling. There's also a noticeable engine stutter and if the AC was cooling, it stops cooling. If the car is running, usually the tach will jump back on when I reach higher rpms and the AC may start cooling again. When you wiggle this relay in the socket, the Tach'll work for a while before acting up again. Tried contact cleaner, no help. Mechanic says replace this too.
Anyone out there know better?
