The connector is located on the drivers side just above the parking brake pedal.

Hope this helps.

LOW pressure port should be next to dryer,,pass. side

I am guessing you are talking about air conditioning ports?, if so, word of thumb,the port on the large diameter hose is low side and the smaller diameter is the high side or pressure side.

Most lkeley it is the solenoid that controls the link that has siezed. It gets the worst of conditions down there, so will need a clean and service if possible - or replacement.

the knocking that you hear is the compressor turning on it is low on oil it needs serviced

i dont know what a lp is ,,,but the low side service port is on the largee ac line ,it is the smaller of two that u service the ac,follow the large line/hose untill u come to the small service port this is the one

Should be near the compressor. The high side is by the filter/dryer

42-45 low side and 200 high side would be nice but the heat being like it is look far 250 to275 and that is pushing it...if the low side service port is like 2 feet away from high side(whitch i think it is on this year) your low side could reach about 52 ,so this wold be normal

You probably have the low side of your bulb blown check the bulb if that dont fix it ck your conector.if your dimmer switch was bad it wouldnt work on eather side. I will try to get you a diagram for the fuse box. PHIL.
