Replying to: motonation (May 28, 2008 6:39 pm) Hi,   Thanks for the above information, hopefully it is the same issue I have with my 2000 Quest.   Do you happen to have detailed instructions to remove the HVAC controller ?   Thanks AJ Replies to this message: motonation (Jun 20, 2008 4:24 am) aj4611 (Jun 20, 2008 5:10 am) motonation (Jun 20, 2008 5:18 am)

Replying to: aj4611 (Jun 15, 2008 5:41 pm) You're welcome AJ. I don't have our van here today, but sometime during the next couple of days I will provide some instructions - its easy - only eight or ten screws or so. I can put up some pictures if you'd like.   Be back later. Replies to this message: aj4611 (Jun 20, 2008 5:10 am) motonation (Jun 20, 2008 5:18 am)

Replying to: motonation (Jun 20, 2008 4:24 am) Hi,   I did manage to get the HVAC controller out - I had a Haynes Repair Manual and the instructions to remove it were slightly out of place.   The connectors on the HVAC controller look fine, I made sure that all the connectors are snug and not loose. I am waiting for the weather to give me some high temps in the 90s to really confirm if things have changed..   I will keep u posted.   Rgds, AJ Replies to this message: motonation (Jun 20, 2008 5:18 am)

Replying to: aj4611 (Jun 20, 2008 5:10 am) I'd put some dielectric on that connector shown in my pictures if you still have it disassembled. Can't hurt! And it was definitely my problem.   (Our van is at the tire shop right now, having tires put on at 245K miles; I think this might be our 6th set of tires)   Be back later tonight sometime.
#36 of 51 2002 mercury villager front ac blower not working. by sunbeam3 Aug 13, 2008 (2:20 pm)
I would like to know if anyone would be kind to help me solve this problem, I was on a long road trip. and my front ac blower stop working. I check the fuses, everything check out find. when I start the car the front comes on and fade to stop working. The rear AC is working just fine.

Replying to: sunbeam3 (Aug 13, 2008 2:20 pm) This sounds like a connection problem whereby a broken or cracked lead heats up due to a poor connection to the point where the expansion from heat causes the connection to separate. You don't mention whether or not it does this in all speed modes or one. If in one or two speed modes it could be the front blower motor resistor network that needs to be replaced.
#38 of 51 Front Cold, Rear Warm by haugh Aug 19, 2008 (8:54 am)
99 Villager Sport, 3.3l, 139k miles. I have had my A/C system leak out refrigerant (likely shrinking seals) over a winter to the point where it was blowing warm when we used it the following summer. I took it to a mechanic to get belts and seals and water pump replaced and have him look at the A/C system. He asked if it was working fine the previous summer (which it was) and suspected seals that were leaking. He asked if I wanted it charged and because the wife HAD to have A/C before a trip we were taking in a couple of days, I said yes. It is a 134a system but he filled it with Red Tek (I did not know). The system worked fine for a while but now the rear A/C only blows warm while the front continues to blow cold so I know there is no leak in the refrigerant lines. I am suspecting that the rear expansion valve has become plugged and needs to be replaced.   Has anyone else experienced this or gone through this repair? The expansion valve is under $10.

Replying to: 46ts (Jan 11, 2007 1:08 pm) I'm looking at the same issue. I just replaced the blower resistor and it's overheating. Did you find the solution? Replace the blower motor?
#40 of 51 rear blower not working by skybiz1 Mar 30, 2009 (3:02 pm)
1995 Villager rear blower not working. Front panel works fine but will not control rear blower also will not transfer control to rear panel. Temp control and upper and lower conrol button work fine on rear control. blower motor works when connected directly to 12v dc.

Replying to: skybiz1 (Mar 30, 2009 3:02 pm) This is a known problem (at least I think your facts apply).   If you have No Rear AC Blower Motor on your Villager/Quest (look under SubTopics) Replies to this message: skybiz1 (Mar 31, 2009 11:49 am) steve_ (Mar 31, 2009 12:31 pm)
