I am trying to remove the factory radio in a 1998 Mercedes SLK 230. I have radio removal tools, but I don"t know if I have to remove part of the dash trim/ panels or not before I can pull the radio...

I have a 1998 SLK230 and I can't adjust the vents for cool air. It only comes out hot. Could this also be related to an inability to lock or unlock either door form inside or remotely?

thanks

1975 450 SLC. When AC turned on, cool air comes out off center vents but heat comes out off both the right and left vent. Help please, Harold

The duo-valve needs to be replaced. It controls the coolant flow to the heater core. They get stuck open or the rubber diaphram comes apart and no longer seals. In either case it allows the coolant to enter the heater core and causes hot air to blow out of the side dash vents. See if the inserts are available separately.

Check one of the fuses in the bonnet. There is most likely an electrical contact problem. You will need a fuse wire replacement

2003 Ford Explorer XLT Air Conditioning vents blow hot and cold

It sounds like the control motor switching from hot to cold is stuck halfway in between the two temp settings. You will have to take it down and replace it, it is mounted under dash passenger side near the blower motor.

My 99 grand prix air condition only gets gold on the passenger side and blows hot air through the left three air vents.

same motor for all vents, try changing the filter for the ac,its located under the hood, in between the firewall and under the black plastic wiper cover on the left hand side. Remove it first to see if it works, if it does replace it. If it doesnt work or blow more air the fan might be going bad. I have 2 grandprix and that was the issue with mine.

99 jeep grand cherokee limited blows cold air on drivers side. Passenger side vents feel warm but it doesn't blow. Also has problems defrosting.

You may have clogged vents. Is their alot of junk on the floor tword the engine bay. This could be clogging the inlet to the vent.

Another issue could be internal a clog down inside of the dash vent systems or you could have vent door operating issues.
