Why do we think on the high side of a relay driver?
Generally, we think on the high side because we usually place the power switch in the power lead as in Fig 1. The same may be accomplished by locating the switch in the low side or return lead as in Fig 2. When controlling relays via logic etc. it is far easier to interface to the low-side driver.
What kind of relay driver does electroschematics use?
Included are the following: High side toggle switch driver, low side toggle switch driver, bipolar NPN transistor driver, Darlington transistor driver, N-Channel MOSFET driver, and ULN2003 driver.

If that reads good, then it must be the fuse that goes to the fuse panel. This is in the underhood electrical center, called the LBEC2 fuse.

Why is my power window switch not working?
The most common reason for one window to stop working is the switch, so this should be looked at by a professional mechanic to have your power window switch replaced. Once the mechanics replace the switch, they will test the windows to make sure the rest of the system is working properly. 3. Window works from master switch only
