Replace it, the brushes in the motor are worn out.

check burn fuse first and if ok check blower motor resistor

2000 Jeep Grand... | Answered on Mar 03, 2015 | 49 views

did you scan the PCM first.
rear lights dead, not dead dash brake warning light.

check all fuses first?
the fuse is in the cab or under hood
so lets find out where, i open FSM book, and look at schematic
brake lamps
the fuse is in JB box. cab fuse box.
its marked clearly as. Fuse F23 Brakes.
the brake switch is on the brake pedal.
if the fuse is good, 12vdc on both sides.at all times.
then the brake switch is open
if its output is 0v brakes pressed.
if the output is 12v then the switch is good, and the wire
are bad, to the rear.
or both lamps burned out or both sockets bad or wires cut
from trailer hitch hacks,.

IS THAT a malformed DTC error? what?
where did you see that?
  1. -in the cluster VFD
  2. autozoned..
  3. a real scan tooL , where>?
P1450? (seem, to me its not P, zero hits)

the first letter matters, P is power train,
the factory service manual covers that, read that yet.?
click here

click emission.
see those codes now?
if you dont have a scan took ask your local mechanic to scan
it, and advice you.

each code tells the tech when tests he needs to do.
the codes do not ever say < replace part X
only in year 2050? when AI systems evolve.
we still need humans to diagnose all complex systems.

or take the classes an not have to ask ?

If you have no brake lights, and you've checked the fuses and the bulbs then, the problem is likely a the brake light switch on the brake pedal arm. The switch needs to be adjusted or replaced.
Hope this helps.

Are you loosing fuel pressure, or spark ?

2000 Jeep Grand... | Answered on Feb 24, 2015 | 177 views

old post, i like the question,
the answer is easy on all computers on earth.
the puter (it's a microprocessor really) has DC power
when the capacitors there, discharge, then the processor stops
processing , (like lamp that dies, same way)
so how long, ?
that depend on the size of that cap. and the processor +loads.
so, we dont know that, NOR CARE.

it takes 1 minute on some. or milliseconds others.
on the air bags , way way longer. (by DESIGN)
its like asking,
who fast can my take of water here, drain.
there is NO ANSWER,
with out inputs and facts, not given.
physics 01.

(it also depends on other things shared on power feed if they have caps, so that the total parallel cap values can be very high and slow the discharge,
tricks? (varies by year and car, (design)
short the battery cables, battery disconnect.
some car hit brakes does this (battery neg lug pulled)
other cars head lights. (battery neg pulled.)
but newer cars all that is dead. key off battery out.
relays are open then and only the battery trick works. on new cars.
also on new cars there is a memory bus and a set of fuses
the are hot all the time to every processor in the car./
my Jeep has that. 2008
so only the battery pulled , gets all power dead.

You must remove the entire front bumper and you will want to remove the radiator as well. There really isn't enough room there.

Remove headlights.
To remove the front bumper, there are plastic clips around wheel well and under the front bumper. Then there are a couple of bolts under the hood and two bolts on the side (look from wheel well up). The whole thing comes off as one piece.

I was able to move (twist) the A/C condensor out of the way and not drain it.

When the engine is cool open the Radiator Cap and make sure it is filled to the top with Coolant. From there locate the Coolant Reservoir and make sure it is filled to the level marked on the side of the container. Now this is where the confusion comes as "burping" the cooling system comes from decades ago and is not necessary now. When the Cooling System is properly filled the system will purge its self when it runs and shuts down. The important part is run the engine to completely make the nominal operating temperature and when it cools the Coolant will move around. This is where most people open the Radiator Cap to check which introduces more Air into the system. Do not open the Radiator but rather check the Reservoir which you should see actually lost Coolant is it gut sucked into the Radiator thus topping off the system.

take your vehicle to your local radiator shop and have them pressure test it very cheap test and it'll tell you whether you got a leak or a head gasket or anything else bad I'll make it easier for you instead of telling you all kinds of things to do that you may not even know how to do

Do you mean the brake pedal goes down to the floor quite easily and you literally have no brakes?
Do you mean the brakes are there but there is no power assistance?

If, as you say the hydraulic lines haven't been disturbed and no fluid lost, I doubt the problem is hydraulic and if the pedal feel was merely spongy that is probably what you would have said rather than you have no brakes.

Are you sure your new brake servo unit was identical in every respect to the one you removed including the internal push-rod and any seals and gaskets?
If there was something that needed transferring from the original to the new unit before fitting did you remember to transfer it?

If you are confident you got everything right there should be no reason to remove the unit and start again.

Even if the unit is faulty and providing no assistance the brake pedal should feel normal as with the engine switched off.

If this is the case you need to check that the front chamber is being evacuated of air and there are no leaks. If the usual checks prove negative then you could have a faulty unit.

If you need more advice please provide a more thorough description when you return.

Looks like a problem with the idle air control stepper motor. Many times its just dirty and needs to be cleaned.

2000 Jeep Grand... | Answered on Feb 03, 2015 | 168 views

Can be a bad O2 sensor. Check with a scanner which shows live data the 1-1 and 2-1 (upstream) sensors. Good sensors show a rapidly fluctuating voltage from 0.2 to 0.8 V. When the sensor has a steady voltage, then its most probably bad. There is no check engine light and no fault codes set?

2000 Jeep Grand... | Answered on Feb 03, 2015 | 139 views

Check all fuses. Not sure where they would be on a jeep but also check chassis grounds and any others. These can screw up random things. Last but not least just run the wires and see if they are crossed with another wire or broke at any point. This might take some time one of these should fix it. Hope this helps
