Where and how do you get to the main relay for a 1989 4dr civic?

Answer 1

Are you refering to the PGMFI relay? The Honda parts department will refer to this part as the main relay. The parts computer includes PGMFI in the name. I recently replaced this part in my 1989 Civic LX. The relay was located on the driver side under the dashboard, against the wall where the door closes. 1)I had to remove the driver door pin so it would open all the way. 2)I took off the plastic screw holding down the plastic dashboard cover. 3) Remove the ash tray carefully in its various sections. I was able to pop out the drawer, etc. I was the able to use a Phillips screw driver to take the ash tray frame out of the space. 4) Remove a hold down bolt under the dashboard. By removing these various parts and bolts you should be able to shift the dashboard cover just enough to reach the hold down bolt of the relay. 5) Use a drop light to see what you are doing. 6) The ashtray is removed so you can ease out the plastic hold down on the relay wires. You should be able to pop out the small plastic nipple out of the hole without breaking it. You can pop it back in when retracing steps at the end. 7)Use an appropriate size wrench to remove the hold down bolt on the relay. This is tedious and takes time since there is not much room to move. 8) Ease the relay down into sight and unplug the wire. Plug in the new relay and retrace steps. I replaced this relay because the car would start perfectly when cold. If it ran for only five minutes and was turned off the car would not start. I would turn it over, pause and turn over and it would start. Once the relay was replaced, the problem stopped. My advice is buy the relay first so you know what it looks like. You have to bend down sna d strain to see it, but it is visible. The auto repair undistry is full of itself. I do not trust anyone.
