The brake line on the front left has rusted out. It was replaced & the brakes bled. Today I have no brakes & the pedal is to the floor. Is there a “special” way to bleed the brakes? 

Answer;

Often when one line is rusted others are close to rusting through. When the line is repaired this places increased pressure on the rest of the brake system and another leak develops.

If the pedal is allowed to go all the way to the floor the piston seals in the master cylinder will stroke along surfaces they don’t normally reach and these surfaces may be corroded and pitted from moisture in the brake fluid. When the pistion seals drag over this corrosion they may tear causing a lack of pedal.

The best way to go in a situation where there is corrosion in the brake system is to replace all suspect parts at the same time and bleed with a vacuum or pressure bleeder.

Question:

2001 jeep cherokee limited both heated seats stopped working and passenger side blows cold air only. what do I do?

Answer:

These 2 problems are not related. The heated seat system and the heater/ac are separate systems. If you have the dual zone heat/ac system (passenger/driver) then the temperature blend door pivot has broken. I see this a lot in these vehicles. It will involve removing the dash and hvac unit to be able to replace the blend door. This is something you should have your dealer do, or an independent technician who is familiar with this type of work. The part itself is not expensive but the labor will be (about an 8 hour job). As far as the heated seats, what I see is the actual heating elements burn out. There is an updated repair kit to fix this that you can purchase from the dealer.

Generally to diagnose this, I apply power to the fuel pump from under the car at the fuel pump wiring harness using a Power Probe while having a fuel pressure gauge hooked up so I can see if it is working. (in 90% of these cases it is the fuel pump and not the relay, this is why I check the pump first). Also, while your under the car and at the fuel pump wiring harness. You can have someone cycle the ignition key and check for power going to the pump from the relay. If you do not see power coming from the relay, then the next step is to check for power going to the relay. If you have power going to the relay by not coming from it(when you cycle the key) then the relay is bad and will need to be replaced.

I am hooking up a starter in my saturn 2001 sc1. I need to know what colour the wires are for the security wire and the tack wire is that comes from the ignition. the car will not start with the starter. I have the other wires hooked up. it will turn over but it will not start  Already Tried: nothing. I just want to make sure that I hook the right wires up the right way. Would I have to cut the security wire. That is what the starter manual is saying. It is saying that i cut the wire and hook the input to the cut wire that goes to the ignition and the output to the other end. is this correct.
