The power distribution center, or fuse block, located under the hood houses most or all of the vehicleâs fuses and relays. It contains a relay for the ECM that is powered up when the ignition key is turned to the on position. This ECM power relay acts as a switch that supplies power to the ECM.
How to Tell When It's Time to Replace Your Water Heater. A water heaterâs lifespan depends on several factors, including water quality, water temperature, and maintenance. As such, lifespans vary anywhere from 8-15 years.
I live in MA and the average water heater replacement install is about $100. It takes about 30 to 45 minutes. Maybe you are including the heater? Cost for a water heater here is 3 to $400. I personally have not had to pay for the replacement heater, as I buy one with a 5 to 7 year warranty, and they usually need replacing, just under my warranty time.
