Yesterday,everything on my '87 300SDL was working fine.A/C included.This morning...I turn key and glow plug lights,but the buzzing sound that goes with it is not 1/4th as loud as it usually is.Car starts fine.Moving along,I notice the speedo is not working...nor is the odometer.Next,I put on theA/C..no cold air,but the hot works!Are these all related?What's up here??? Thanks for any help!!

Try turning your key slightly toward position 1, and see if the power comes back. You could have a bad switch.

The main concern here is the lack of cold air.Also,I'm wondering if the weaker glow plug buzz or speedo problem have anything to do with the lack of cold air.Any ideas?
