Maybe a shorted speaker causing the power amplifier inside the radio to shut down or a speaker wire shorted to chassis and last the internal amplifier of the radio cd set faulty by itself... set volume to zero power it off take out the radio cd set; remove the speaker iso plug leaving the power plug only in and power it on if necesary turn again the volume down to zero and wait if it keeps turned on it a speaker problem if it shut itself off again then you go for a repair or a new one
The click you are hearing is most likely the start slenoid making contact, however you should short the large wires @ the solenoid to make certain the starter still doesn't run, if so try tapping the starter with a hammer to shift the comutator a litle and try to start. Even if it now starts the starter will continue to give you problems so the proper fix is change the starter
Check ALL fuses. Check the wires on the back of the unit, especially ground and "key on" wire.
It may be an Intermittant shorting of the units ground wire, which would cause the unit to totally shut off and on whenever the short happens. Shouldn't be a hot power wire shorting, because it would have blown the fuse and wouldn't work at all. There is a 12v signal wire that tells the unit when your key is in the on position or the acc. position. The "key on" wire. That wire may be causing the unit to turn itself off and on if it is getting an improper signal. it may also be a problem with the cassette player itself.
perhaps it has more to do with temperature than mere pressure? figure out how far your wife has to drive before it leaks, drive half that distance away from your house and turn around. by the time you get back home the leak location will be giving itself away. note whether your wife runs the A/C, with the parking brake on, or anything else which will affect the temp under the hood.
It would be best to pull the radio fuse leaving it out for several minutes then replace it. tis may well fix the problem but if it doesn't you can remove the fuse agin knowing it will not drain the battery over night
See GM TSB 05-08-143-001, If you have Adjustable pedals, especially if they don't work with the memeory buttons, but function with thier own buttons. Its the Brake Pedal Position Sensor is shorted and mesing up the seat module which controls the heaters too. My 05 Suburban had the same issue. Can check by unplugging switch and see if heated seats work .
