A/C delayed cooling.
 

When I start my 2000 C230 Kompressor the a/c blower comes on but after waiting about 5 minutes I have to turn the manual dash control switch off and back on several times to get it cooling. Does that indicate bad switch or something in the temp sensing system/computer? Hmm tnks

Check the cabin air filter, on my 300 sl , i just ahd to replace the ac blower motor because the prior owner had not changed the filter. I bought the car knowing the blower motor was innop. but upon reinstallation I didnt have good airflow, removed the filter and it worked great. I conclude that the old motor died from over work & no air flow. I'm ordering a new cabin air filter.
