Forgive me, but I looked all over this site for the wiring diagrams I swear I once saw... but the whole DIY section seems to be lost. Last spring I replaced the blower motor with a new one and the climate system seemed to work fine all summer... now however it just stops and starts at what ever whim it decides. Driving me crazy. Its different than last spring when it was bump related... now I need to look and see what might be doing it...plus since winter is here (sleeted this morning) I have to have defrost. This E55 is my daily driver/commuter. Dispay shows the fan is being told to but thats just a display.

Any ideas on what to look for and test?

Thanks....

It was the blower motor regulator when it happened to my E55. You can get it cheap on Ebay.

Bought my BEHR regulator from AutohausAZ. FCP Euro has it also. Works well!
