#174 of 248 92 Q45 t HICAS STEERING SYSTEM by jcsiii88 Mar 08, 2008 (4:07 pm)
I HAVE A SLIGHT LEAK IN THE RACK, SLIGHT LEAK IN THE PUMP, THEY NEED TO BE REPLACED. HOWEVER, AFTER A SHORT TIME DRIVING, 3 TO 4 MINUTES, THE HICAS LIGHT COMES ON AND THE ENTIRE POWER STEERING SHUTS DOWN. RUNS FINE, JUST NO EASY STEER. COULD THIS BE A MALFUNCTION OF THE HICAS PUMP, LOCATED ABOUT MIDWAY BACK UNDER CHASSIS? AND HOW DO I TEST THIS PART, OR REPLACE IT. 156K MILES, SUPER NICE Q, CUSTOM EXHAUST, LOVE THIS CAR, BUT...

#177 of 248 Headlight quit working please help by damd56 Mar 19, 2008 (6:31 am)
My 02 Q45 passenger side headlight quit working recently. It started by coming on and going off at certain times. If I played with the switch turning it off and on it would come on. However now it will not do anything? What are my options. I would like to repair it myself. Replies to this message: lakeland (Mar 22, 2008 1:43 pm)

Replying to: damd56 (Mar 19, 2008 6:31 am) Damd56, It is one of two things. The bulb or the ballast. Normally it is the bulb. They are expensive. You can switch the bulbs around an see if it does the same on the drivers side. Then it is the bulb. You should replace them in pairs! A good online place is plasmagarage.com Ivy
#180 of 248 97.5 Q Will Not Start by gatekeepa1 Mar 26, 2008 (7:14 am)
I attempted to start my 97.5 Q45 one morning, and the engine turn over, caught, ran rough for a minute or two. I turn the car off, and attempted to restart the engine, however the ignition turned over and over, but the car wouldn't start. I can't tell if there is a problem with the injector or the fuel pump has gone out (car has 125K mi). Is there a anything that I can do to test the injectors or the fuel pump? Or, is there something else that I should check? Thanks for any feedback on my problem. Replies to this message: knowspinzone (Mar 27, 2008 5:26 am)

Replying to: gatekeepa1 (Mar 26, 2008 7:14 am) If you turn the key to the "ON" position you should hear a slight humming coming from the area of the fuel tank for a few seconds. If you don't hear any sound, your fuel pump is bad.
