Hi all, recently i changed my manual steering to an electric steering so that i can adjust the steering through the switch to a more comfortable position...but I can't adjust it...now here comes the problem i was told by my mechanic that the reason why the electric steering switch is not functioning is due to im using a MANUAL SEATS tht doesn't have the module...so what im confuse is: 1. does all the electric seats selling from the half cut does hav the module included? 2. If yes, may i know which of the parts under the electric seats that i need to look at before i buy the electric seats? 3. Also, if i bought the electric seats do i nid to buy the memory button and install it to my door? Is it necessary? Thank You.
