Blower Motor Repair

BLOWER MOTOR REPAIR

It’s finally starting to rain in Chico again. That means Fall and winter will soon be here; that means cold weather is near. By the end of October, it’ll be chilly for sure. By November, it’ll be full wet weather and jacket season. You’re preparing for the new season, so shouldn’t your car be drafted too?

Rather than wait until you need it, get your vehicle’s heating system serviced long before the cold gets here. To help you out, we thought we’d review the essential elements of the average car heating system. That way, you’ll know what to look for if anything goes wrong in your HVAC heating or cooling system.  We are one of the best auto shops in Chico !

The parts of a car or truck heating system are relatively common overall. Many features use shared methods, like hot coolant from the engine to make warm air with the blower. There is certainly a vast and wild nuance between the systems in different vehicle makes and models, but for the most part, it goes like this:

1. The ignition system powers the car and all the electronic components, including a blower motor repair. Power and signal pass through the blower motor fuse to protect against power surges;

2. On to the blower motor relay, then the blower motor resistor or blower motor control module for fixed speed and variable speed systems, respectively;

3. That charge is then passed to the blower motor, which takes air in from the outside (filtered by the cabin air filter) and then passes it through the vent system;

4. This air passes over an A/C condenser to produce cool air, and some air is passed over the heater core to provide heated air. Finally, they are mixed using the temperature blend door, which controls airflow mixing.

5. Temperate warm or hot air is finally passed through vent doors into the cabin through the passenger/driver side, windshield, etc.

A water pump is also part of the heating system in that it controls the coolant flow used to heat the air in the first place. A thermostat valve also controls when to allow more coolant into the engine. Finally, the cabin air filter keeps the air from being contaminated from the outside while allowing the system to take advantage of the heat. In rare cases, it can even cause temperature control issues, significantly when air quality has noticeably decreased.

Several different issues can occur related to the blower motor and heating system, some of which may require professional service:

• Coolant leaks can bring the coolant level in the coolant overflow bottle so low that the HVAC system doesn’t work. It is possible that this can be resolved simply by refilling the engine coolant, but fixing a coolant leak itself may require much more effort in the long run.

• Dirty coolant may require a coolant flush to expel fluid clogs in the cooling system. This has been a real problem lately, with the summer heat hotter than ever. Unfortunately, many people are finding they’ve been running low on coolant for way too long, which results in a much higher density of contaminants and very obviously dirty coolant.

• The temperate blend door can become stuck or clogged, often requiring someone to get in there and pick the gun out to get it working again.

Have you been having heater problems in your vehicle? Not hearing the blower motor, failing to get hot air, never feeling warm air in the cabin?
