To those of us who aren't automotive wiring wizards, wiring looms, switches and relays can look like bird's nests. A great precaution to take before you go digging into the rabbit hole that is your car's wiring, is to give the culprit circuits a good blast of contact cleaner. Thing's like power window switches can gunk up over time and stop your windows from operating properly, rather than replacing regulators, switches and wiring harnesses, it's worth a quick squirt of contact cleaner first to make sure it isn't just in need of a good clean.
