Recently had an alternator and starter replaced in my 1999 nissan now the heater stays on even when off
Unrelated, unless the mechanic screwed something up doing the work. Take it back to the shop, 99% they will deny doing anything wrong but don't know what else to suggest
Thinking it could be the control switch
The blower fan stays on? Your thinking is correct
If the fan stays on, Its definitely something they did. If its just rolling in without a fan, its normal. You probably just never notice.
