GirsMJ86 Posted April 12, 2006 Share Posted April 12, 2006 well when i got my hands on my 86 i found a few things wrong with it. :roll: one of them is that my fan switch only works on high. and that my C/C does not kick on. i was told they are relays but i wanted to see what everyone here thinks. also the switch in the door jam to turn the lights on in my driver side door quit workin the other day. so now when i open my drivers door the lights don't come on. the passenger side still works. so i was just wondering how i got to the wires for that switch? thx alot. alex Link to comment Share on other sites More sharing options...
mjeff87 Posted April 12, 2006 Share Posted April 12, 2006 Fan switch problem is the resistor pack/switch attached to the blower motor wiring inside the cab on the passenger side. The cab light is probably a corroded door switch on the driverside, that isn't making a good ground to complete the circuit. No comment on the CC, as I don't have that creature comfort :D Jeff Link to comment Share on other sites More sharing options...

pingpong Posted April 12, 2006 Share Posted April 12, 2006 fan,CC, and interior lights..... Whats that stuff :shock: Check the ground, and the vacum lines on the back of the heater control panel to see if they are working properly. CC, mine never worked either, and I never tried to get it to work. Patrick Link to comment Share on other sites More sharing options...
mjeff87 Posted April 12, 2006 Share Posted April 12, 2006 Alex, For the blower, check this link: http://www.geocities.com/chmwatson/FAQs ... k_fix.html That's a repair you can make if you want. If not, replace the whole resistor pack. HTH, Jeff Link to comment Share on other sites More sharing options...
87manche Posted April 12, 2006 Share Posted April 12, 2006 I did that repair on my escort. Won't take long. I would recommend a resistive soldering iron. Like a "cold heat" style. A traditional soldering iron will destroy the thermal fuse if left in place too long. The other option is to put a heatsink between the thermal fuse and the conection your soldering.

GirsMJ86 Posted April 12, 2006 Author Share Posted April 12, 2006 well ill give it a shot. and just to my luck i have one of the "cold heat" irons. ill let ya know if it worked. if not then i guess i have some parts huntin to do... or just swap the one out of my 88. alex Link to comment Share on other sites More sharing options...
GirsMJ86 Posted April 12, 2006 Author Share Posted April 12, 2006 well i took it out from under the dash and its even easier then that guide link. there is no soldering! they just pull out and plug in to these brackets. ill get some pics up. right now I'm off to the local radioshack for a fuse. thanks alot jeff for that link. alex Link to comment Share on other sites More sharing options...
GirsMJ86 Posted April 19, 2006 Author Share Posted April 19, 2006 ok i lied, it wasnt easy at all to get out. the thing was crimped in there. and i couldnt find one in any of the local stores. so i took the one out of the 88 and put in inplace of the one in the 86 (just the fuse not the whole relay because it wouldnt work). well now to say it works on all fan settings but it will ONLY blow out the defrost vents. it won't change to vent vents or bi-lvl or heat or anything other then the defrost vents. anyone got any ideas here? alex Link to comment Share on other sites More sharing options...
DirtyComanche Posted April 19, 2006 Share Posted April 19, 2006 That's a vacuum issue. Have fun. Link to comment Share on other sites More sharing options...

87manche Posted April 19, 2006 Share Posted April 19, 2006 check the vac hose that runs under the battery to the vacuum ball in the bumper. That's the one that did it for me, and whereit's located seems to make it pretty vulnerable. Link to comment Share on other sites More sharing options...

If you have cruise control, you probably have two of the cans mounted next to each other. Link to comment Share on other sites More sharing options...
GirsMJ86 Posted April 19, 2006 Author Share Posted April 19, 2006 thanks eagle. i will have to go look into it today or tommara. whenever i get the time. while i am at it i might as well look into why my c/c doesnt want to kick on. alex Link to comment Share on other sites More sharing options...
GirsMJ86 Posted April 19, 2006 Author Share Posted April 19, 2006 does anyone have the vac hose layout pics for the 2.8L? i have no clue where to start for this after looking at it. thx alot. alex Link to comment Share on other sites More sharing options...
Pete M Posted April 19, 2006 Share Posted April 19, 2006 email me and I'll reply with every vacuum diagram I scanned back when my scanner worked. petermontie@hotmail.com Link to comment Share on other sites More sharing options...
GirsMJ86 Posted April 20, 2006 Author Share Posted April 20, 2006 well this is gonna be fun. i compared those pics to my v6 and i either don't have most of those color of hoses anymore or i need to do some serious hunting. i only looked at it real quick. i don't have much time to work on it right now with school getting ready to end and having big papers due. :evil: alex Link to comment Share on other sites More sharing options...
