Well, its a hard quiestion, but to be truthful, there is no cure haha
I assume your car heater is blowing cold air, when the heater is on. It seems that, you have air on your coolant. that air pockets blocks the cooland to travel through your heater. it may be a sign of a bigger problem such as blown head gasket in the old cars, such acura legend
There are too many different reasons. But it seems your unit outside is not working properly.
Check your cooling fan
How did you change the thermostat?
there seems to be a short in the electrical system, i would start by checking the heater switch,
Ok, I got the answer to this question. It seems that there is not a heater control valve in the heater hose line.
How does the heater system work on S-10 Chevrolet? What seems to be the problem with your's?
There seems to be a short to ground in the wiring somewhere.
Seems like there's a short in the wiring somewhere.
In most new cars, it starts with removing the dash. I liked the way the old Ford (60's) heater cores slid out through the firewall on the engine side after taking off two hose clamps and two sheetmetal screws...those days are gone. Seems that, anymore, they hang the heater core by a string and build the car around it.
I would first check either the controls to the front heater core or a blocked front heater core. It could also be a blocked or missing heater hose to the front heater core, although that seems quite unlikley.
Yes, a mole will go into a house. I have one in my house right now, it seems to act like a mouse would eating what ever food boxes it can find. It seems to be living in my house and goes to sleep or out during the day. It seems to be most active in the house between 4-7 am and I guess about 11 or midnight. Also, it seems to come out more if the lights are off. So, the answer is Yes, they will go into a house. (BTW, I'm gonna try to catch it and keep it as a pet. Luckily he's not too shy.)
