1998 C280, W202, Evap Temp Sensor Replacement
Hello -
Seeking help for some A/C related problem: Basically the A/C is available during initial startup for a few (5-10) minutes and then gradually the air warms back up. Diagnostics on Actual Values on the A/C Push Button Control Module suggests that Evaporation Sensor (Code 5) gives a reading of 146 and stays that way during running (this value also noted before turing the igniton on). I suspect this is an 'out-of-range' value. While I do not know if this sensor malfunction can cut of the A/C?? I request some tips on- 1) Where is this sensor's exact location? 2) Can a novice handle this replacement without a serious PITA? 3) What is the causal relationship between this malfunction and A/C All other functions IMHO work perfectly well on this ACC - Please Help - either online or offline (enkad@yahoo.com) |

Fairly easy DIYer, the drivers under dash panel is the only part that needs to be removed to repace the evap sensor.
VERY common failure on 1996 & later cars. 210-830-07-72 should be the correct part

My 98 C280 has a similar problem. It will cool for a few minutes, then the air goes warm and no further cooling. Can you tell me how to check the codes on the A/C Push Button Control Module you mentioned?
Thanks! |

These threads are very helpful on the AC diagnostic code display.
