Cabin Heating

Palmers Auto Repair Example : Vehicle Heating and AC ControlsThe system designed to provide heat inside your car has become quite complex since the early days (1950’s).  Although the basic principle of piping hot engine coolant through a heater core in the cab of your vehicle hasn’t changed much over the years.  However, the challenging locations and technical skill level needed to replace these components certainly has.  Often the entire dashboard must be removed just to access the housing where the heater core sits.  Then there are also your control cables and vacuum lines, the air blending doors and air ducting.  Sometimes the repair process will require that the AC refrigerant be recovered and then recharged during the heater core replacement process.

Needless to say, proper diagnosis of your heating system is key before work begins.  There are many reasons why your vehicle may not be keeping your feet warm.  In the unlikely event that you need your entire dash removed to replace the offending part, we at Palmer’s Auto Repair pride ourselves in always installing the highest quality under-dash parts.  And while we are there we’ll check to ensure that any worn or vulnerable parts are brought to your attention.  We’ll make sure that all of the intricate functions of your dash are working correctly when we are finished.

Did you know that proper cooling system maintenance can prevent the heater core from failing?  When anti-freeze gets old it becomes corrosive and the heater core is often the first component to corrode through.  “Long Life” coolant doesn’t mean forever.  We have also seen long life coolant gunk up and clog heater cores, so it isn’t a long term fix-all.  Corrosion and building up gunk can be prevented by back flushing a vehicles cooling system and replacing the coolant.  This protects the heater core, control valves, and plumbing.
