The ignition and blower fuses in your Chevy Express conversion van may keep blowing due to a short circuit or an overload in the electrical system. This can be caused by damaged wiring, faulty components like the blower motor or ignition switch, or even water intrusion. It's advisable to inspect the wiring for any visible damage and test the related components for faults. If you're unable to identify the issue, consulting a professional mechanic is recommended for a thorough diagnosis.
Under the hood. In the blower motor harness connector.
Because something on that supply line has a problem
The blower resistor controls the speeds of the blower motor Hi-resistance lower motor speed Lo-resistance higher motor speed
The resistor for the blower motor on a 2004 Chevy Express van is typically located under the dashboard on the passenger side, near the blower motor itself. It can usually be found mounted to the HVAC housing. To access it, you may need to remove some panels or the glove compartment for better visibility and reach.
It really needs to be checked out but it probably is the blower votor.
On a 2004 Chevy Express 2500 van, the blower motor resistor is typically located under the dashboard on the passenger side. It is mounted near the blower motor, usually within the HVAC housing. To access it, you may need to remove the lower dash panel and possibly the glove compartment for better visibility.
when my car did this it was a blown fuse
Sounds like a short in the wires somewhere. you will need a diagram & have to trace them.
The blower motor speed resistor is burned out. The resistor is located close to the blower motor and is easy to change. Your local auto parts store will have that part for you.
If the 1990 Chevy Lumina is blowing the DIS 10 Amp fuse when the ignition is on, check to make sure that all wires coming from this fuse are grounded properly. Also check to make sure the starter is wired properly. There could also be a loose wire in the dash near the ignition.
Your blower motor working even after the car is off is a good sign. This means that the car's system is preventing your car from overheating.
The blower resistor is internally shorted to power and needs to be replaced.
