I have a 2010 jeep grand cherokee with factory keyless entry. Lately it has been unlocking itself overnight. By coincidence, I saw the headlights come on one night, checked, and the door was unlocked again... just as if I had just clicked the unlock button on the keychain remote.
So, I took the battery out of the remote, made sure the doors were locked and went to bed. A few hours later, I check the car and the doors are unlocked again.
This typical? Seems like the control unit for the keyless entry in the Jeep is acting up to me.
Is there a way that i can cut the power to the keyless receiver to disable it while still having the power locks work (pushing the lock/unlock button on the door panel)? I have been searching online and can't find a fuse to pull or the location of the keyless receiver for the Jeep.
Any help will be appreciated. Thank you

Like a brick

Mine's on the right.
I can has Turbines?Stupid thing uploaded a photo by accident and apparently "Delete" doesn't delete.
Just replaced my fuel injectors & exhaust manifold. Now occasionally its stumbling at idle from 300-1000 rpm, and when I switch it into park it jumps to 1200 for a moment then back down. Sometimes it just idles smooth at 700-800 rpm.
No hissing or anything from exhaust gasket, no leaking from injectors that I can see. Fuel rail pressure was fine yesterday before changing injectors out.

I unplugged the TPS wire, and its idling & shifting seemingly fine. I imagine that points to TPS then. I'm going to let it dry out all day to see if I got some powerwash water in it from cleaning the engine before swapping the exhaust, otherwise I'll order one. PITA! ha.

I bet you have a bad solenoid. It is easy to check and fix.
"To check solenoids in transmission without removing pan - removed plug off TCU that is located Rt side dash under clove box -with key in off pos.- volt/ohm meter check pos. lead terminal C14 converter clutch solenoid should read 11-15 ohms, terminal C15 shift solenoid #2 should read 11-15 ohms, terminal C16 #1 shift solenoid should read 11-15 ohms make sure you have good ground on - lead. If solenoid cks good problem is else were loose wires or tps" originally posted by McRay
That is for a cherokee though.

Is it possible to wrap the exhaust manifold with heat wrap while it is in the car or would one need to remove it to do so.
Just thinking about all the heat generated in the engine bay and wondering if that would help.
Looking at the manifold, looks pretty much impossible to wrap in place.
Just wondering if anyone has done that.

So random question. I need to replace the rear main seal in my 96 zj 4.0L. It has about 250K miles. Is there any reason to consider replacing the pump while I'm in there, or is the lifespan for the oil pump in these more or less indefinite?
Thanks in advance for the advise.

Ah ha! Yeah we washed the manifolds to get all the grime off since my VC leaks a hair. I unplugged it and let it dry out for a while and drove it without it, and it seems to somewhat have fixed itself. Had a store run the codes, got P0740 & P0122 which both seem related to the TPS and TCM lock out related to the TPS. They couldn't clear the codes with their tool, any way I can? Yank the battery leads for a few minutes? Just want to see if it comes back. Going to disconnect all the plugs and let them dry. Might have gotten some water in there the other day.

Use your accessories, sensors, flywheel/flex plate and manifolds. You'll need to plug the hole in the back of head where the old temperature sending unit lived otherwise it'll shoot coolant everywhere
