Different specific symptoms indicate different problems. A garage like Sindall Truck Service can diagnose the issue and replace parts for the vehicle owner. Contact us to set an appointment.
Some of the problems are easy to fix. If the fan turns on and can be heard, but no air blows from the vents, the issue may be a clogged cabin air filter. That’s especially likely if warm air can be felt at the vent but it simply is not flowing into the cab. A technician removes the old filter, clears out any leftover debris, and adds a new filter. Not only dust, dirt, and road grime can get into the filter, but leaves, seeds, and other organic debris as well.
If the temperature gauge needle doesn’t move up to a normal range after driving the truck for a while, the thermostat probably needs to be replaced. Sometimes, a problem with the thermostat causes overheating, but other times lack of heat may be the problem when the device malfunctions. A lack of heat indicates the thermostat has become stuck open. This is safer than the thermostat becoming stuck closed because the engine will not overheat, but it’s still inconvenient during the winter.
Another problem that technicians who provide Truck Repair Service in Westchester PA may find is a heater core blockage. If the temperature gauge needle is in normal position and the vent fans work, a lack of heat is likely explained by this issue. The heater core is a small radiator that has the function of keeping the interior of the vehicle warm. Flushing sediment out should get it working properly again. The technician disconnects the hoses to the heater core and, typically, uses compressed air to blow out the thickened coolant and other grime that has accumulated there.
