Temp panel lights off, when they come on radio goes out
The lights on the panel for the heat/ac are off when the car turns on. Noticed this started about 2 days ago. Occasionally, when they lights turn on they have turned off the radio. On a few occasions, if i tapped the panel the light have come on... is it a fuse or a loose connection

The panel where the ac/heater controls light up with 2 tiny bulbs placed right behind the round controls that turn the ac/heat on and the one that turns the setting from red to blue. theres 2 screws holding the panel on the dash and those are right under the radio. You'll need some needle nose pliers to get to the bulbs and they sell the bulbs at walmart.
You need to repair the heater core with a soldering gun.
If you do not have heat, or only have heat, IMHO it is most likey the AC/heater control unit. This is the part which has the AC/heat control buttons and knobs.
Easy Diagnosis: The easiest way to verify this is to turn on the radio, press and hold the power on/off button and press and hold the scan-up button for a second (full second). The word "A/C TEMP" should appear on the left of the display and a number from 0 to 16 on the right. I suspect yours will have the number 0 (or 16 if heating only problem) displayed no matter where you turn the temperature control knob. If this is the case you could turn the temp. knob to full heat and see if it goes to 16 after pushing down or to the right on the knob. In a working system, the number moves evenly in increments of 1, from 0 to 16 as you turn the temperature knob.
Easy Fix: I was able to take mine out and solder 3 loose connections to fix it.
The beginning steps are the same as for any radio removal procedure and check for loose connections.
have the vehicle scanned for trouble codes most auto stores such as auto zone/advanced auto do it for free/ur heat and engine light might be connected the control panel uses cable--elect and vacuum connections to move and actuate dampers and switching between hot and ac
when turning ac on the fans come on automatically ,sounds like u need to bleed cooling system ,get the air out ,look near goose neck or whre ur top hose goes in and look for a bleeder,fill up coolnat jug and radiator and loosen bleeder when nothing but coolant comes out (no air ) the shut bleeder off,,, if this doesnt help replace thermaste and repeat proceedure
There is a tiny little peanut shaped light bulb inside the radio that provides the light for the dial, it is replaceable, you will need to remove the radio, then pull the top cover off the radio chassis, the bulb is under the cover.
The fuse for the radio/CD/DVD is seperate from the AC/Heat. Open fuse box under hood on right. follow fuse schematic to ac fuse position (note there are two so if not one, then it is the other) use the fuse puller that is in the fuse box, then replace the fuse. Good luck.
