Heater blower

[tucknroll]

Hey 69 charger here.  My fan blows good heat but not hard enough.  Do the blower motors get weaker and maybe a new one will blow harder?  Thanks

Check the resisters.

It's working on high and low so I think it's just worn out

Temporarily connect the motor directly to battery voltage and compare the output to HIGH on the control panel.

Good idea thanks

Question...
 Is it an A/C car?

[tucknroll]

Where do I check the resistors please?

[tucknroll]

So I connected it straight to the battery and it turned super fast but I plugged it back up and it ran slow again.  Any ideas?

follow connectors

[John_Kunkel]

You've proved that the motor is good so now look at the resistor block or the fan switch. It's not uncommon to find the spade connectors at the fan switch fried.

How do I bypass the resistor? Running on high is fine with me
