troubleshoot head lamps on 1988 grand marquis? Not working...fuses OK
Hey Bill==You have several electrical problems. I suggest you take it to a garage. GoodluckJoe
Assuming the pump won't engauge. Check for blown fuse. If OK, turn A/C on and bypass the low pressure cut off momentarily (10-15 secs max) to see if A/C pump engauges. If it runs OK, charge the system. If it makes noise, replace the pump. If it still won't come on, I'd check the relay and switch out.
The term troubleshoot means to figure out why something is not working.
The first stepÊto determine why a fan is not working would be to check the fusebox. If there is no fuse, or the fuse is fine, the next step would be to look at the switch controlling the fan. If those appear fine, the fan itself may be busted and in need of repair.
Determine what is not working properly, then determine why.
The first thing that you need to check will be to see if the both the a/c compressor and clutch are working as well as checking the condition of the drive belt............
