My ABS light and parking brake light only come on when my blower is turned to 1,2,3,or 4 and the blower wont work(no air). But if my blower is turned to 0 both lights turn off. If i turn the blower to speed 5 the blower pumps at max like normal and both lights turn off. Brake fluid level is good and the A/C works ice cold(usual) only when blower works at level 5. Help please?
Blower motor, ABS light on and parking brake light on? on 2003 GMC Sierra 1500
Need to fix the blower first! Under glove box you will find the blower motor, beside it is the blower resistor, that needs to be replaced along with the wire connector, both are aval. from GM dealer or NAPA. Give parts man vin number to get the right one! It is called a Blower Resistor with harness connector. Very common problem on this vehicle! After that have ABS system scanned for codes. (if needed).
