I noticed about two weeks ago that the blower motor and power windows do not work right after the vehicle is started. There are no lights lit up on the instrument panel. After about 5 minutes of running time, the amber ABS brake light comes on, both the blower motor and the power windows start working. If I turn the vehicle off and restart it, it does it again. This happens about 90% of the time. I asked the dealership and told me that they never heard of such a weird thing. Is this something that I can fix without getting gouged at the dealership?

A/c compressor works fine and the blower motor works and shutdown right? it is the problem with the blower resistor or with blower motor relay. try to direct the resistor irrespective of the speed. hope the problem may be solved.
Hi Victor, I'm glad to help!
First Victor, let's make sure its not the blower motor. Run power and ground from the battery to the blower motor and see if it works, if it doesn't replace the motor. If it does work. NOTE: Most vehicles, when the blower motor quits works its because the blower resister is bad. The fuse that powers the motor is usually a 30 amp fuse, on some vehicles its under the hood on others its in the fuse box inside the vehicle. Before going through all this first check power and ground at the blower motor connector to see if your loosing POWER or GROUND. Because you need to know which one your loosing. BUT, if I were working on it and knowing what I know about blower motors not working I'd replace the BLOWER RESISTER first. Hope this helps and have an awesome day Vivtor.
Chk for power at the blower motor electrical connector. If no voltage, check the blower motor resistor, its within the blower motor vent (this controls power to the blower motor). Also, in theses vehicles water may have damaged the blower motor itself. Inspect the blower motor for proper function.
the blower not working on settings 1-3 is the blower motor resistor. this limits the power provided to the blower motor itself to change the speed. at setting 4 it is getting full power. since it quit on 4 also, i would still say the resistor needs to be replaced first, then see if the blower comes back. you may also need a blower motor. if you have a voltmeter you can just turn the switch to 4 and see if the motor is still getting 12 volts. if it is and doesn't run, it needs a blower motor too. if it's not, then its just the resistor
The blower motor, as you have probably seen, is under the dash on the passengers side. While in Park with the parking brake applied:
Turn the Key On with fan blower set to High. Locate the blower motor and wiggle the electrical connector. If this brings the blower motor to life, a new blower motor is needed. This, if applicable, is a common failure that matches your symptoms. The new blower is simple to replace, although it is never fun working under the dash.
If you have a 12 volt test light or DVOM (multimeter) you can check for power at the electrical connector. You should have battery voltage (12+) with the blower set on high. Always use a known good ground when testing for power. If you have power (key on, set to high) and no blower operation the blower motor needs replacing.
The resistor you replaced is a very common failure on these.
