I have just replaced the power steering pump and then the power assist brake module through the firewall. Now my park lights are on full time,until I turn on my lights,then the drivers side goes out. Also,the drivers blinker is more rapid than before.. I have checked all that I know.. which I know,is very little. Thanks for your help.

Wires were disturbed for sure.
Older Cars Flashed slow or wouldn't flash if a Bulb was out, Newer vehichles with Electronic Flashers, Flash quick when a bulb is out, or wiring to bulb is disconnected.
Park lights usually come off the Headlight Switch.
Put the 4 way flashers on and walk around vehicle and tell which are working, replace or check that bulb is good.
