Cold Weather Car Problems

Two common complaints in cold weather are doors that stick closed and the heater blows cold air -- no heat.

For doors that stick:
Before cold weather clean the door and trunk gaskets (rubber seals) and the surface the gaskets meet with soapy water. Rinse and dry completely.
(* A Must: ...Leave the doors open until surfaces and seals are completely dry.)
After seals and surfaces are completely dry, spray with a silicone spray that can be bought at any auto parts store, Wal Mart, etc.
Repeat this at least two times....and now you are ready for cold weather. If you live in an area of an extended cold weather period recoat both surfaces with silicone spray every 4-6 weeks.
Note: If the weather is already cold, this procedure may be done in a heated garage where the seals and surfaces will completely dry before the silicone spray is applied.

If your heater is blowing cold air instead of warm/hot the first thing to do is:
* Check coolant level. If it is low add coolant and pressure check the cooling system for leaks(hoses, radiator, thermostat housing, and don't forget the water pump and freeze plugs) .
On many vehicles low coolant will not allow coolant to flow through the heater and the engine temperature may show cold.
