Electrical Issues

[Ketoe]

After all the motors and transmission I have stuffed into this thing, although the car is running fine, I am having some electrical issues, which are as follows:
Dome lights stay on after I start the car, I open/close doors and they go off.
Dome lights stay on after I stop the car when I leave it unlocked (past the normal 15min), goes off if I lock the doors.
Central locking button doesn't work after car is started, but does if I close doors and lock it before starting the car, once started the doors unlock.
Locking function on the FOB doesn't work unless I press unlock first, but works if I don't start the car.
Four-way flashes come on after I start the car.
Heater control unit blows fuses, but lights on buttons work when headlight are on.
So far I have done the following:
Replaced alternator/battery
Replaced Flasher/Central locking unit
Replaced the Ignition Switch
Changed battery in FOB
Replaced Climate Control Unit,, VAC Blower Motor Resistor and the fuse.
On a side note, since the radio was trash I installed a Head unit, don't recall if the problems were there or after it was installed.


I have to think, except for the heater, everything else had to be related in some way, just don't know what.
