Hi All

Since several months to now, I notice a noise in the dash like something knocking. I found that was one of the step motors was done. I replace it with a used one with the same ref. The vendor assure me that the step motor is working well. I fitted it and now the noise has gone but now there is very small cold or hot from the dash to face.
I read somewhere I can't remeber where, that when instaling one of this motors it needs to recalibrate by the dealer or someone with a land rover tool. I own the allcoms ant it seems it is worthless
Can someone give me some directions abou this please?
Thnks in advance

Cheers
