No problem Mark. Glad you found value and appreciation in my video. All the best. Arjun

Remove the kick panel driver side and passanger side and see if can see the servo motor for the blend door. Chances are motor went bad. Replace the servo motor. Should work Hopefully you can get to it by removing some interior trim peaces, otherwise you might have to pull out the whole airbox like i did. I wish you luck. Let me know how it goes.

Maybe the servo motor might be the same, but the box and door assembly, i highly doubt it. Manufactureres source parts and sometimes sub assemblies from same suppliers but design assemblies in house specofic to their vehicles only.

I agree.

Your going to have to submerge the bolt heads in a penatrant oil. Build up a damn around the bolt head with clay or plasticine at least 8 inches past if you have the clearance and pour wd40 or mix of trans fluid and acetone 50/50 mix. Let it sit for a week or two and than remove and try again.

Is your a/c circuit charged with refrigerant ? And Is your a/c compressor kicking on with ac switch at head unit pressed in ?

Did you check the air cabin filters located behind plastic cover in glove box. Those filters get clogged and need to be replaced every so often. In the winter i would just remove them outroght. This will help improve your heating sotuation this winter.

Have you removed the bolts on the engine compartment side of the firewall holding your hvac box in place ? I think there are 2 possably 3 bolts.

I ended up inatalling new chinese made boots on it at the 1000km mark the following year. But im more than confident this repair soloution would have lasted allot longer had i left it on the bike.

Chinese boots are garbage quality

@@crackedthieves totally agree. The ones i bought are still holding up. But its well understood chinese products are inferior to what the west used to make 30 years ago.

One of the servo motors for air box is accesible from driver side. If your noticing air not being dorected when you switch dial or air temperature from hot to cold. you can remove servo motor from box still installed and seats in place. Just remove the driver side front panal to gain access to corner of air box that has this servo motor on it. Not sure if this servo motor is temperature motor or door flap motor for directing air. Cant remember.

@@mechman4 Thanks. I know the Fresh/recirculate actuator is by the windshield vent under the upper dash trim piece, so I think the one under the wheel is the blend door actuator. Thanks!

@@mechman4 Thanks again for your help. I replaced the source door actuator so it works and no longer just clicks when I switch between Fresh/Recirculate. I can see that the blend door actuator is turning the blend door just fine when I turn the Hot/Cold knob. Unfortunately, I don’t get anything out of the front vents and I can’t seem to redirect the air no matter what I have the knob set to. This means I still have a problem with the mode door or mode door actuator. It seems they switched from vacuum to electric mode door actuation in 2001 and mine is a 2000. I can’t seem to find any info about where the mode door or the actuator is for the 2000 model. It’s maddening! Looks like I might have to do a deep dive like you after all. :(

@@emmettturner9452 Sorry to hear about the future project ahead of you. But take heart. If you have cordless tools and air tools, tearing apart the inside of your van, although allot of work can be done in a weekend. Make sure you have all your replacement parts ready to go so your vehicle doesnt sit out of comission while you wait on parts. I would recomend replacing your heater core and hard to reach servo motors if your going to go into this disasdembly. You dont want to be doing it twice because your heater core later fails down the road.

In most climates that is enough to keep the windshield defrosted In northern regions of Canada its never enough. Gm knowing they were going to sell this vehicle north of the boarder should have done a better job designing the hvac system. Sadly they did not. At least not on the pontiac montana.

@@mechman4 I noticed that some configurations duct air under the seats to the back passengers and then the auxiliary heater in the back has vents that blow forward to the front seat from the ceiling. I wonder if this explains the weird configuration in your duct work. It may be that they expect the driver to control the auxiliary heater for their comfort.

Not 100 % sure to be honost. It was quite some time i made the video and dont remember the details behind the interchangabillity of this engine. From.what i can remember the ballancer shaft 4 liter engine was exclusive to the ford 4x4 market. But.it might bolt up to a non 4x4, you would need everything though, the ballancer shaft the chain the oil pan the jackshaft. Everything ! It might be allot easier to remove a 4x4 complete engine from vehocle to instal in your 2x2.

MIT Engineers realized they just lost the game to the rednecks

The ford 4 liter had a ballancer shaft. If your ford bronco has the 289 cubic inch displacement engine its a v8 5 liter which does not have the ballancer shaft in it. Not sure if you meant 1968 or 2008. Ford didnt make the bronco in 1968. Do you have any check engine lights.come on with your drivabillity issue ? No power above 3800 rpm ? If no check engine light on and no stored code to retrieve which would tell you the problem. Could be fuel delivery problem. Check your fuel pressure followed by replacing fuel conponents like fuel pump and pressure regulator if pressure is low.

Hello friend. I used the repaired rubber boots for about a year or 3000km before deciding to replace them with the new chinese ones i bought from ebay. But there was no real.reason to replace them since in more than confident they could have lasted even longer, maybe even to pressent day now. I did have a problem sealing where the bolt heads go. For theses areas i recomend using a little silicone when installing to help seal it. Other than that your repair, if done well should last you a couple years or longer, im sure.

Your explorer has a ballancer shaft. Ford used the engines with ballancer shaft almost exclusively on all 4x4 SUV and trucks. Only some passenger cars got the ballancer shaft engines

I imagine your right. Just my luck I bought a 2002. 2003 or 2004 would not have been an issue.

@@michaelgrantham5344 yes but all the Pontiac products from 1999 to 2005 share a lot of the same parts the HVAC is very similar and dose share some the same design and parts

It's been a long while since I worked on these engines. As much as I would like to answer your question for you. I dont want to give you incorrect information. Is there a ford dealer in your area that you could ask a mechanic at ? I will research it a little on my end and see if I can find anything out regarding your question.

This automotive forum descussion suggests that only ford 4 liters with ballancer shaft were fitted to 4x4 modal vehicles. So although not 100% certain, ita unlikely that your ford mustang has a ballancer shaft engine unless someone (previous owner) installed 4 liter into your mustang that was out of a ford explorer 4x4 modal. www.ford-trucks.com/forums/488499-sohc-4-0-l-balance-shaft.html

@@mechman4 thats awesome! i have a 83 XJ1100 im very interested in your build i look foreward to updates

@@oneslowgp Might be Christmas time or longer before I can edit it upload another video. I haven't been documenting or editing to much on this build. If your interested, email me at mechman4@gmail.com I can send you a few pictures of what I have done so far.

Well done ! These days you can find repair videos on almost anything on youtube. With world economy these days, don't unnecessarily spend your money if you can repair your old stuff. Well done on salvaging your honda sender. 🙂👍

I know EXACTLY what u mean

If you didnt remove the ballancer shaft chain and the tensioner was still keeping ballencer chain taught/tite so no chance that chain could have jumped teeth, than your good. no worries. the timing procedure in my video is only if you have removed the ballancer shaft chain or if you believe ballancer shaft chain has jumped teeth due to a failled tensioner like was the case on my engine.

+mechman4 than you. brother tomorrow ill put everything back. then

hello George, sorry for late reply. I believe you may be able to check your timing marks align by removing the oil pan and visually inspecting dots align when cylinder number 1 is at top dead centre on compression ignition stroke. however correcting this allignment if out may require removing timing chain cover to remove balancer shaft bolt to reposition balancer shaft gear to crank gear. Allot of work to correct less work to check. hope that helps.
