Left & Right Window Regulators for 2013 Skyline V36 Coupe

[Therry]

Both windows operate normally while the engine is running but start to sag as soon as I switch off. 

Does anyone know of reasonably priced replacements or other brands that will fit?

Replace your battery.

Sag as in the windows start to slowly open themselves, or they're just slow to go up/down with engine off?

MBS206:-

The windows start to slowly open themselves.

GTSBoy:-

Battery is new since Dec.

That seems like a very special issue!  Does it affect both sides?

Either way, I would disconnect the driver's side switch and see if it still happens, noting that might require removal of the whole door card which is a bit of a pain (it does on V37 and HY51)

it affect both sides.  Driver side is worse.
