My recent aquisition, an 84 300sd, had its AC converted to R134 according to the previous owner. He said he thought it had a small leak as it was not cooling well by the end of last summer. When I set the climate control for full blast AC I do not hear the customary click of the compressor kicking in, or see a change in idle. This what I'm use to hearing in my other vehicles. The air temp coming out the vents is whatever the temp is outside.

Do I walk into a MB repairshop and say, "make it work, again!"????

I need AC. but she is 24 years old...I don't want the repair to exceed the value of the car.

BTW, the heater temp control works great as do the blower speed/auto controls. The pods are stuck so that I get great defrosters....and some air out the side vents.

Any info would be appreciated.
