ok so summer is coming and you know how unforgiving summer is in california. i have a 1987 190e and i was thinking doing an ac job to is or just simply let it go. However i am still trying to consider doing the ac job.

here are the symptons:
-cold air do come out of the vents but it is not cold enough.
-the ac clutch engages but it intermittently disengages
-when the engine temp is above 90 the compressor does not engage at all
-on the center vent, the right side of it blows colder air
-in some cases the vent blows cold and hot air mixed together.
-belts are tight

what do you think should be done to this? a recharge? a complete do over? let me know

thanks,

e
