Gonna try and check out the fuses today after work. Hopefully this is the problem because that would be the cheapest fix.

 

I am having the same problem with my 2003 H2. However, in my case the both directional signals lights come on (left and right, like the hazzard signal is turned on but it's not) when the left turn signal is turned on, but works normally when the right is turned on. Also, the keyless entry has to be re-programmed every couple of days. maciej have you figured this out yet? I also have the same problem with the mirros folding, but I think it is un-related.

 

How about trailer connection wires? Could any wires have rubbed and worn thru to ground?
