Aloha,

I recently bought this 1990 300E about a month ago. The AC was cold but air does not come out from center ventilation. Suddenly theres no Cold air that comes out from the vents. The heater still works cuz everytime I turn up the climate control the air gets hot. Fuses from fuse box inside hood by the left fender are all good. Checked R 134 freon, and its got pressure. Looks like all connections are connected. What else do I need to check and is there a troubleshooting manual for this car?
I need help, Its a little warm here in HAwaii.

Thanks for your help

Try the expansion valve.

When you have the temp set to cold does it blow warm air out ? Check to see if your compressor is running and are you getting any bubbles in the drier site glass?
