Fan speed control is not working Inspection Service

The most likely cause of fan speed control failure is a resistor failure at the fan’s motor, although it can also be a defective control switch or burned-out fan motor.

Common reasons for this to happen:

  • Blower resistor malfunction
  • HVAC control panel is bad
  • Blower motor is bad

What to expect:

A top-rated mobile mechanic will come to your home or office to determine the source and cause of the fan speed control issue, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs.

How it's done:

The mechanic will perform a thorough inspection of the HVAC system. The mechanic will check for motor operation by removing the connector and checking the condition of both male and female sides. They will probably test motor operation by connecting a battery via alligator clips to the motor’s plug pins and see if it runs direct from that source.

If the motor works fine, the next step is checking the resistor. The mechanic will unplug the resistor from its connector and check for burnt terminals. That often signifies a bad resistor. To check resistor functionality, the mechanic will use a multimeter set to the resistance function, then measure the resistances from a common point on the connector to the various pins to make sure the required Ohm values are up to spec.

The mechanic will be looking for an “open” condition (infinite resistance), which reveals a defective circuit.

i am well satisfied with Mr Smith working on my car(s). He replaced the Jaguar fuel pump like an expert, and then he diagnosed the VW bug ac compressor and fixed it on the spot. I would recommend him to anyone with a car issue

Incredibly nice and took the time to show me the problem, including comparison pictures between my unit and what a new unit should look like.

He knows what he's doing. Very polite and explained everything. I would no doubt use him again. I highly recommend him.
Mazda Miata - Heating AC - Peoria, Arizona
We are so thrilled to have found Peter as our new mechanic. He is very thorough and knowledgeable. He is also friendly, professional, and extremely honest. He explained to us exactly what services were needed on our vehicle to repair the air conditioner and provided us with an written estimate of the cost. He literally saved us thousands of dollars in repair costs. A local major competitor quoted us a repair cost of a minimum of $1,400 and said that the cost would go up to $2,400 if they discovered an additional part was required. Peter charged us only $202, plus performed the work at our home. The air conditioner in our 2004 Mazda Miata has honestly never worked so great--it always blew out warm air. We just assumed it was how that particular car was manufactured. We would highly recommend Peter to anyone who is in need of an experienced and honest mechanic.
