A couple of suggestions on this one: If your Jeep has the Auto Temp Control (as you mentioned). Might want to look at: Blower Motor Controller and OR your Blend Doors. By the way---- There are SOME EXCELLENT Posts on this Board dealing with this Topic (might want to do a SEARCH). Just a...

Yes --- A Motor going OUT would DRAW excessive Current---Causing the Resistor to: Burn out. Resistors (an electronic component) are RATED by the Manufacturér in: 1. OHMS And 2. POWER Example: A Resistors Specs would be: 330 Ohms and 1 Watt. IF you EXCEED the Power Rating FOR any Length of...

Previous Poster is correct. If the Resistor were Bad. --- ONLY the High speed position on the Switch would work. (12V is applied directly to Fan Motor). Most likely it is the Fan Motor Itself or the Switch. Easiest way to narrow it down : Pull Electrical Connector from the Fan Motor ---...

It sounds Like an Electrical Issue.... But, when it won't start --- have you checked the Pressure on the FUEL RAIL? Also, Are you getting Spark at ANY of your Plugs? Codes? On the Issue of Rebuiling your ECM --- It can be done. BUT, ECM is an Electronic Device --- Certain Precautions MUST...

Good Question. (In fact it is two questions!) Poster has asked --- How do we KNOW we have : Fuel Pressure and Spark? You will REQUIRE a HELPER and some simple HAND Tools. Have your HELPER sit in the Jeep. Remove the Gas Cap. LISTEN for the Fuel Pump to come ON -- while your HELPER cycles...

Any UPDATE on this one? It has been around a week --- Just wondering IF original Poster got the Problem with Jeep--Straightened out?? Hope he did! -- JB

You might be able to go slightly Higher -- Under SEVERE Driving Conditions. Probably about -- 220F -- On a HOT Day - while climbing a hill! I would expect the Normal Transmission Temp. To be around: 180 to 195F. Several Factors come into play: 1. Thermostat Temp. (195?). 2. Do you Have...

Just. Like Steelheadz said: It is simply a process of Elimination! Three primary compnents in the FUEL GAUGE: 1. Gauge Itself. 2 The Sending Unit 3. The WIRING to Interconnect it all. You HAVE Replaced the Fuel Gauge and the Sending Unit -- Correct? Then in that case --- It is PROBABLY the...

Your HARD STARTING IN COLD --- Could be a case of -- WEAK IGNITION. Is this Engine the: 2.5L. F.I. Motor?? Some suggestions on the Hard Starting WHEN Cold Issue: 1. Is the Ignition Timing set correctly? (Factory Specs) 2. Replace Dist. Cap, Rotor, and Plugs. 3. Check Plug Wires -- IF BAD...

From what you have described --- IT sounds like more of an Electrical issue than a Fuel Pump proiblem. Your Jeep is Fuel Injection-- Correct? Have you checked the Fuel Rail --- to see if you have Good pressure? Your flickering Headlights --- Definitely sounds like an Electrical Issue...

Sounds like you are -- Back UP and Running. Great. But, as Previous Poster Pointed Out ---- You MAY very well -- NEED a NEW Battery in the. NEAR Future. Some Batteries will become -- WEAK after 3 or 4 Years of use! -- JB

That. Sounds GOOD! Do you FEEL that both Problems are now FIXED? You probably should VERIFY (with VOLTMETER) that your CHARGING Voltage Is Between: 13.8 and 14.2 Volts when Jeep is Running!! Does JEEP start EACH time -- WITH OUT pushing on Starter Relay?? Also -- VERIFY Battery Terminal...

Did you say --- You were told the Problem could be the : Neutral Safety Switch? (NSS) Does your Jeep have an - AUTOMATIC? Neutral safety Switch is ONLY installed on Jeeps with AUTOMATIC TRANS. It is LOCATED on the PASSENGER side of the AUTO TRANS. There will be Some wires going to it!! It is...

Well --- In this case. --- I would PULL the Battery. 1. Have the Battery Charged. 2. After Charging the Battery -- Have a LOAD test performed(Confirm Battery is GOOD) 3. CLEAN ALL Battery Terminals (with battery Term. TOOL) Install Battery back in Jeep. Does JEEP start NOW? IF it does -- CHECK...

Well --- Let's see what can be done here. First things --- First -- Welcome to: Jeepz !! You mentioned that your Boss had to give you a JUMP to start your JEEP. When WE have an ISSUE like this --- ALWAYS start with the Battery. You mentioned your GAUGES went NUTS on your Dash! O.K. --- I...

YES --- On Many Jeep Models --- The Voltage Regulator is BUILT-IN to the PCM. Glad You got it all straightened out. It is Unfortunate that you NEED to Sell the Jeep. But, I can understand why you feel this is necessary. If it is any consolation --- Your Problem was a Fairly Rare One --- We...

Is. The Faint Squeak --- Maybe a Clicking NOISE? And Rich--- When they said it ----- IS ALWAYS THE STARTER !! THEY WERE. WRONG. It is NOT. ALWAYS the Starter! You have put a COUPLE of Starters in this JEEP -- and the Problem is still there! There are several Components in the Start Sequence...

Nice looking RIG!! And: Semper Fi ! ! Thanks for the Post! -- JB

Yepper! I'm glad you got it going--too! That was a TOUGH ONE. Thanks for the Feed-back. On my Post of: 12-1. --- I mentioned the PCM could be the cause of this problem (Item # 5). Gentlemen: If we THINK about it -- In HINDSIGHT-- It amost had to be a Wiring Issue or a BAD PCM. The...
