Ford Ranger / B-Series :: 2004 - Heater Won't Warm Up While Idling
Dec 31, 2012
My '04 Ranger has over 240k on the odometer. Runs great and has never given me any issues. Everything checks out OK - all the fluids, filters, and whatnot are in good shape. No CEL or any other indication that anything is wrong (except for maybe the IAC valve and clutch slave.)
I've noticed, though, that when I fire it up in the mornings to let it warm up while I scrape the ice and snow off the windows, the heat/defrost will not blow warm air. It doesn't matter how long I let it sit, it will only blow ambient air through the ducts.
When I get going down the road, however, the heat kicks in, after a bit, and works very well!
I've not found anything that would indicate an issue with the blend door or any other component and this is the first vehicle I've had that did this.
Is it normal for a 4.0 SOHC Ranger to do this? Or is there something I'm missing?... It's not really that big of a deal, but I do find it a bit odd that it would do this.
I mentioned the IAC above - I think it's "sticking" every once in a while and, when it does, I'll hear a loud "thump" right before it idles down to around 1k rpm. I can't see how this would affect the heat, though...

I have a 95 4.0 EFI inside of my 83 Ranger. Once the motor warms up, it starts to have an idle issue. I have to press the gas, in order for it not to cut off. Here is a video I posted a while back. A person suggested that it could be the MAF needed to be cleaned. I did that, and it did not work.

I have a 1996 Ranger that the Heater/AC blower only works when the outside air temp is above 45 degrees. I have replaced the relay, and the blower motor resistor. What could be causing this?

backed out of the garage fine later in the day went to put it away started hard would not idle and only rev to 2500 .cleaned map sensor,egg valve tested and it works.cleaned the IAC and that works ,fuel pressure is 58psi. starts hard it would idle now it doesn't dies, no code . with 58psi could the pump still be bad? it has 18 pounds of vacuum. where is the vacuum line for the fuel pressure regulator on the motor?

I am having a problem with the heater on my 98 2.7 Intrepid. Will not blow hot air when idling (just warm). After several minutes of driving with heat on air temp goes from hot to warm. It might just be me, but it seems like the air flow is cooler coming out of the defrost vents than from the dash/floor vents. Thermostat has been replaced (proper operation verified before installing). Had to replace gooseneck and heater coil supply tubing due to a leaking bleed valve. There appears to be NO air in the system.
Heater core was backflushed, there appears to be no restriction. Hose temp on exit line is approx. 15 deg. cooler than supply line when fan is running. Blend door actuator was replaced last spring (motor shorted). When temp control is moved from hot to cold temp changes drastically and door can be heard moving. On-board ATC diagnostics indicate all is good. Engine is running at normal operating temperature, not overheating or running cold. Is there a cabin filter or inlet supply for the air that could possibly be obstructed? Air flow seems adequate, not restricted. AC works fine.

My 03 ranger with a 2.3 I4 does not want to restart when it is above about 80 deg outside and engine is warm. Will crank, but as soon as fuel in line runs out it stalls, like a vapor lock. After about 45 mins can push start normally( has manual trans) but have to wait about 2 hours to use starter to start.

2002 Ranger XLT auto 3.0 will not start after it has run awhile, Was very intermittent at first sometimes six months would pass, sits for and hour or so and would start right up and run great. Lately it is becoming more frequent. Good fuel press, good spark, I have changed the coil pack, fuel relay, filter , am at a loss.

I have a 1994 Ford Ranger 4.0L 4x4, 130,000. I love this truck but about a year ago it started not starting after it warmed up short distances in the summertime? It start right up on cold crank...Runs smooth idles like a champ...but if i shut it off..wont start for 20 to 40 min??? It doesn't happen in the winter months??? So I changed the fuel pump, filter, relays. I feel like it has something to do with the Ignition Control Module. Would that come up in a code?

I have a 1994 Ford Ranger XLT xcab with a 4.0 engine.It will take off and drive in the freezing cold but when it warms up it will only go in reverse.Once in awhile it will go into drive.What seems to be the problem. I had also backed up over a railroad tie in an icy parking lot but still drove away.

My 88 2.9 ranger keeps heating up badly while idling. Was waiting in the drive-thru at Wendy's and it was taking them longer than usual, the temp guage started climbing closer and closer to 'H'.. I revved it up a bit to a fast idle (1500-2000rpm) and it did not work much... figured the gauge was being screwy. But when i finally got my food and started moving the truck was pinging..it really was hot..
But as soon as I got her moving at a steady 40mph, engine cooled back down to normal temp as if nothing ever happened..i put an extra wide two row aluminum radiator from a 4.0 explorer in it, fan clutch is not very old, no coolant leaks that i can see.. can't figure out why it heats up so much so fast at idle. Not enough air or coolant flow?

so I have a 1987 2.9L Ranger that likes to stall out when its idling after reaching temperature. Ive replaced all sorts of sensors (IAC, Coolant Temp, and PCV) and so far no luck. I was trying to figure out what the relearn procedure was for the IAC or get an input on any other possible sources of error. I haven't changed TPS yet.
What the engine does is when it gets up to temp, the engine will start to loose speed, and will start to shutter. Then it'll kick back up run fine for a few seconds and drop again, it'll do this for a few minutes then completely just choke out.

, my trucks heat selector lever, that controls the temperature in my truck, is stuck in the cold setting. by stuck I mean, I can try to move it, but it wont budge more than about 1/16" and no more. its really frustrating because of the cold weather here, and I want to have SOME heat in my truck without a bonfire to get it.

My wife's 99 Ranger's heater fan is not working. It was working off and on until now. The fuse is fine. I went out this morning and tested the blower motor for power in --had voltage. Assuming the motor was bad, I pulled it. Before wasting $ and a trip to town, I bench tested it --it works. Now my question: what do I do next?

I seen on this site awhile ago something about a fix for the heater control door, I have a 1996 Ranger and all I have is Hot heat and cannot cool it down with the temperature control.

Got a 2005 V6 Ranger with low mileage. Having a heater problem. We've replaced the thermostat, heater core, flushed the system twice, burped it to get the air out and replaced the hot water valve. The heater works for a few days then it goes cool: not cold. Adjusting "Temp" will make the temp decrease but it will not return to hot air?

I have a 2005 ranger, 3.0 and automatic trans
The truck runs fine until it is warm... runs great down highway... stopping at a light or stop sign is horrible, It will act like the (old term ) carb is flooding out.
I put it on a meter It said tps so I replaced it. then it said number 4 cyl no power so I put new plugs in.... I do not hear any vacuum leaks, and It runs like a top when cold.

1998 Ranger. I have no vacuum to the heater control valve (see link below) and hoses are warm/hot to the firewall. Where to start troubleshooting?

Ok, I replaced the head gaskets on this truck a couple years back and now I am having symptoms similar to the ones I was having then. I am not entirely convinced that this is what is wrong however.
Symptoms:
Truck was idling rough until it warmed up
Truck takes forever to warm up or simply does not warm up
If/when it warms up it operates at higher than normal temp/almost overheats(it hasn't overheated yet)
Heater blows very cold air
White smoke(has been cold outside so not sure if due to temp or coolant)
Overflow bubbled when I shut the truck off, but it has only happened once so far
I am kind of at a loss, but like I said am suspicious of the head gaskets.

My 1999 ford ranger, when started, shakes and then while i am driving. my check engine light is on and reads a #3 cylinder misfire. I have taken it somewhere to get it checked out and they can't figure out what is wrong with it. this problem only happens 50% of the time. I don't know what to do. Also just got a tune up.

OK...When I leave in the morning and the ambient temperature is cool the truck runs fine. When I leave work and the temperature is warm to hot the truck backfires through intake, pings bad, has a miss and a surge and no power. There is no CE light, this is about to drive me nuts. I was just hoping (doubting) but hoping someone else might have had this problem so I don't just have to start replacing things until it's fixed.

I've recently acquired a 1989 ford ranger xlt 2.9L V6 and iv got my elbows deep already..... starts right up and scene its an older truck i let it warm up for a few minutes seems to sound alright so i jump in and take off... well i make it about two blocks and as soon as the truck seems to warm up it starts to sputter and die out... starts back up and idles for a min and i try to take off, but it seems to have NO power and jerks and dies.... so i push to a street parking spot and get situalated start the truck up again and take off only to make it about half a block tell it does the same....
First i think iv run outta gas witch i might of not sure so I walk to station and get three gallons. put in truck and same is happening. so i start kicking myself for not haven any tools with me and i leave tell next day... that night do a little research and get some idea's of what could be the problem'(s) so i start out with things that look like they need tending Badly WIRES, PLUGS, ROTOR, CAP, MAP SENSOR, and now after a whole day in the rain (Northwest BTW) and grease to elbows? 2.9 V6? What step's should i take next?
