Hello. I have a 96 S-10. The blower works very intermidently, and only on high. WhenI turn the heat/ac switch on, my ABS and brake light comes on. These lights also come on when I turn the temperature ****. I have replaced the blower motor and resistor. I don't know what to check now. I used a test light at the end of harness going into the blower, sometimes they're hot and sometimes not. I am confused.

 

did u ever get N answere?
