Why would your heater work but not your ac in a 1993 mercades 190e?

If your heater works but the AC does not in a 1993 Mercedes 190E, it could be due to several reasons. One common issue might be low refrigerant levels, which can prevent the AC system from functioning properly. Another possibility is a malfunctioning AC compressor or a faulty climate control switch. Additionally, a clogged cabin air filter or issues with the electrical system could also contribute to the problem.
