safe
how like the house blows up or something no i thinks its safe and nothing going to break or explode
Of course, set the heater/air conditioner temperature control to cold.
turn the conditioner up
It's obvious that you have problems with wiring. I would start from the heater/AC control panel.
When they lock up, they turn off the lights and set the air conditioner and heater on an auto setting, to save time and energy
Well the heater could be because you have low engine coolant or the thermostat is stuck open so the coolant will not get heated up. As for the AC sounds like you are all out of free-on.
If the heater has a sweet smell it could be that the heater core is leaking engine coolant. When the leak gets worse you will have a wet floor on the passenger side and the windshield will fog up when you turn on the defroster.
no
There must be a gas leak. Contact your gas supplier IMMEDIATELY, if the smell is in a house. If it is in a car, have your mechanic check for a leak.
That happened to my catera too and it was just two blown fuses so get a fuse tester and test the fuses or take it to a shop and have them fix it for about $80
Turn on the heat, and see if the same smell is there. The most likely cause is a coolant leak in the heater core, causing the coolant fumes to get into the ac.
You've got trouble with your heater fan - or the motor that turns it. Same fan for both heat and AC.
Water collects on the interior floor when the air conditioner is used # Air conditioner evaporator drain hose is blocked. Clear the drain hose where it exits the passenger compartment. # Air conditioner evaporator drain hose is disconnected. Secure the drain hose to the evaporator drainage tray under the dashboard.
