    Thanks,

    I have more to add. I checked the brake light fuse 15A and it was cooked. I replaced it and the shift interlock worked when I pressed the brake. I tried it a scond time and the fuse was fried again. Any thoughts??

Hello Joe...The Aveo has had it shares of problems, and this is one of them....NHTSA issued several bulletins on the 04 Aveo...this following is the one pertaining to the shift interlock.....

Make : CHEVROLET Model : AVEO Year : 2004
Manufacturer : GENERAL MOTORS CORP.
Service Bulletin Num : 070730007 Date of Bulletin: APR 01, 2007
NHTSA Item Number: 10022265
Component: POWER TRAIN:AUTOMATIC TRANSMISSION
Summary:
AUTOMATIC TRANSAXLE/TRANSMISSION SHIFT LEVER MAY NOT SHIFT OUT OF PARK (REPLACE BRAKE TRANSAXLE SHIFT INTERLOCK (BTSI) SOLENOID). *KB

Take that bulletin number to your dealer and see if they can help.

Untill you can get it repaired heres a little tip for getting it out of park....There is a a little hole in front of their gearshift lever that can correct the problem, temporarily. It should say "brake interlock release" or something like that. With car running, put a key-size object into it and push down while moving the lever. It does not damage the transmission, it just releases the lock. (make sure your foot is on the brake)

Now for the brake light issue...do you have power at the switch you replaced? If so go to the relay and check there...if no power there it's probably a bad ground.

Also...you may or may not know, but the timing belts on these Aveos are prone to failure at aprox 50k ...these failures have caused severe engine damage.
Good luck...i hope the information i've provided you find useful.
Please time to rate me.

    The brake light switch controls the interlock solenoid... i checked for more public information bulletins released by GM and came up with this...

    The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

    Condition/Concern:
    Shifter Stuck in Park

    Recommendation/Instructions:
    Before replacing any components, verify correct operation of the Stop Lamp Switch. Check for proper adjustment of the switch, poor electrical connection at the switch or incorrect operation of the switch contacts and repair as necessary. It has been identified that the brake switch is more likely the cause compared to the shifter assembly.

    Do NOT replace the shifter unless the brake switch has been replaced or adjusted and the condition returns again.

    Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

    GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

    Since you have already replaced the the brake light switch and the problem still exsists i suspect that the shift interlock solenoid has shorted...Many Aveo owners have had the exact problem...Like i stated previously...contact the dealer and get some feedback. They are aware of this malfunction and should be willing to work with you in getting it corrected.
    Hope this helps.

I have a 2004 F150 supercrew 4x4 and it will not shift into park and when I start it I have to put it into neutral any help Thanks


Sounds like the shift interlock circuit has an issue.

This can be 1 of 3 places

1. The fuse for the Shift Interlock circuit. This is fuse #16

2. The shift interlock switch. This is part of the BPP ( Brake Pedal Position ) Switch that also controls the brake lamps. There are 2 switches in the BPP switch, 1 for the shift interlock, the other the brakes. The circuit in the BPP switch for the shift interlock is the Tan w/ Red stripe wire ( from fuse # 16 ) to Pink w/ Light Green stripe ( to the shift interlock solenoid ).
Test both side of this circuit with a meter ( to ground ) you should have power on the Tan w/ Red stripe wire any time the key is in the Start or Run position.
The Pink w/ Light Green stripe wire should have power any time the brake pedal is pressed down.
If you do not have power at the Pink w/ Light Green stripe wire, you need a new BPP switch.
If you have power with the brake pedal pressed on this wire, you need a new Shift Interlock Solenoid.

Can't get Shifter out of park on a 2005 F150 ford Truck.


If this is a new body style 2004 ( not a heritage or lightning ) did you check fuse #16 ? This is the fuse for the shift interlock switch on the brake pedal.

IF this fuse is good, check the shift interlock section of the brake pedal position ( BPP ) switch ( on the side of the brake pedal lever, usually has a yellow c-clip cover on it ).
The wires for the shift interlock circuit
Fuse #16 to Tan w/ REd stripe wire
Pink w/ light green stripe to the shift interlock solenoid.

If there is power on the Tan w/ REd stripe wire, press the brake pedal down, and check the pink w/ light greens stripe wire for power ( switch is closed when brake pedal is pressed.

If you do not have power on the pink w/ light greens stripe wire, you need a new BPP switch.
If you have power on the pink w/ light greens stripe wire, you need a new shift interlock solenoid.

I have a 2008 chevy aveo that won't shift into gear unless we press the shift lock release. What is causing that and how expensive is it to fix?


It could be a few things....I just had this same problem with my 2008 chevy aveo this week. Also, my check engine light came on the very next day after the gear shifter started locking. I called Bob Bell and they told me that the gear shifter locking is probably due to a sensor going bad that tells your car it is in park. However, after taking my car to my brother-in-law (who has very LITTLe knowledge about repairing cars), we discovered that my brake lights were not working either. He told me that is why my check engine light is on - because it is extremely dangerous to drive without brake lights. We checked the fuses to make sure there was no fuse blown and they were all just fine. So bottom line, the problem was that there is a brake switch under your dash board where your brake is. My switch keeps sticking and will probably eventually need to be replaced. When the switch works properly, my brake lights work fine, my gear shifter unlocks and my check engine light goes out. Not sure how much it is to fix this switch if that is the problem but I hope it helps!

My 2004 checy aveo sometimes does not shift out of


These have a brake light switch that controls both the shift lock solenoid and the brake lamps, so chances are that if it is not a fuse then it is the brake light switch.

2006 Chevy Aveo, can't shift car out of park without using shift release button


You need to replace your BTSI (brake transaxle shift interlock) solenoid. I have replaced MANY and it is the problem 99% of the time. The only other thing it could be is your BTSI fuse so check it first. All you have to do is remove the shifter assembly and install a new BTSI solenoid (couple of screws and two connector terminals) and you will be driving in no time. Hope this helps!!

2004 Chevrolet Aveo Brake lights not working


A couple of days ago my brake lights on my 2004 Chevy Aveo wouldn't work, so I attempted to remove the lamp covers to check the bulbs. Also, before this my shifter would get stuck in park and could only be released by pressing the unlock gadget next to the shifter. Back to the brakes...Well, you open the trunk and remove the two screws just like the manual said, but it was very hard to pull off. There's 2 prongs holding the other half of the light on. The lamp will come loose by prying it (very hard). You think the cover will break, but it'll come loose. The bulbs were all OK.

After much frustration and internet info, the STOP LAMP SWITCH, GM#96436331 ($9.30 at Chevy dealer), which is located under the dash and has contact with the brake pedal, was defective. Once replaced, both my brake lights AND SHIFTING problems were cured. So if the brake lights suddenly don't work or you have problems getting the vehicle out of park, check the switch by pushing the prong (end that has contact with brake) of the switch in and out. If it doesn't retract smoothly...that's the PROBLEM. Good Luck.
