Does anyone know if the evaporator can be replaced through the firewall or is it necessary to remove the dash board? I have a 1989 190E.
Thanks in advance.

 

Our E320 has the same problem. With this car the dash must come out to the tune of 2,500 dollars. With the NW climate we have managed to do without. I hope it's a different situation on your 190...good luck!

 

Well I finally did replace the evaporator. It comes out from under the hood. You do not need to pull out the dash. It was not that difficult. My a/c is fixed and works fine. I replaced the evaporator, expansion valve and receiver/drier. If you have a 190E and need to do this email me at bruno@cressydoor.com and I'll give you the details.
