I feel foolish in asking this, after 2yrs you would think I know this but; when the car is idling in park and you just lightly press the brake pedal, there is a noticeable relay click sound coming from the interior fuse panel. When in gear, forward or reverse, using the brake pedal does not produce this click. Is this normal, have I've always heard this? The car has been sitting for 3 wks while I gradually install two rear view cameras and I just started the car up today. First the brake pedal was mushy, but after riding a bit, that went away. That's when I noticed the loud clicking while testing the pedal for firmness. I'll post up pics of the camera install when I get a chance. Thanks for any replies.

That's part of the "Brake Shift Interlock" system you're hearing, absolutely normal, you won't hear it unless the shifter is in Park.

A mushy feel to the brakes can be caused by corrosion on the friction surfaces, sitting for three weeks is enough time to build up some surface rust and make the brakes feel "odd" until the pads and shoes burnish it off.

Normal. It's the brake/shift interlock solenoid.Not sure of the proper name.
It is the safety feature that keeps you from shifting out of PARK until the brake is depressed.

Come on Mike. I think we were typing at the same time.

Are you sure you're not twins separated from birth? Thanks for the quick replies. I guess I got accustomed to the sound and then had a reawakening after the layoff period. I must be getting old. Ugh.

Felony- You're not alone... I never heard that click for quite a while either..

Bringing up an old post,but....Mine has started to click in all positions, it did this once before with a code(don't remember the #s) cleared the OBD, all problems went away. Yesterday it started doing it again, trans shifted hard for a few miles, then went to shifting normal. No codes this time, still clicking in all shift positions. Any ideas please.

Thanks Bill

The interlock at the shifter could be getting dry and dirty, pop the shifter cover off and give it a shot of spray lube.

scbill. You've got 2 different issues going on. The shift detent solenoid in the console may be fixing to fail.
The hard shifting is most likely the result of the CEL. Need to identify the CEL number and correct that cause.
It's doubtful that the 2 issues are related or affect one another.
