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

re;c280
 

Can you tell me how to get the A/C fault codes on my 97 C280?

Thank you for the very prompt response! Some follow-up questions-
1)Is this the root cause of the A/C malfunction problem?
2)Any words of advice or precautions while taking out this panel?
3)Any special tools required?

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.
