heater problems
so i was having issues with my heater, all the lights work but nothing happens when you turn it on no sounds or nothing so i swapped it out for another one same problem so i just tried a 3rd one and it still dosent work..:wallbash: i checked the big heater fuse and tried swapping in a differnt one and it didnt help.. this is really pissing me off what else could it be?
|
you mean the blower motor? if you have tried 3 blower motors, perhaps the logicon is bad?
|
no i tried 3 logicons i didnt try swapping the blower motor..but wouldnt you still hear the air mix motor changing when you use the other buttons?
|
you should be able to hear the air mix change i think. does the blower motor come on? I think it may also have a relay somewhere.
|
yeah when i go to turn the blower on it dosent kick on at all and there is no sound what so ever and when i push the selector buttons there is sound either..im lost on what to do next please someone help its F%$$# cold out
|
anyone know if there is a relay or another fuse?
|
Have you tested to see if you are getting voltage to the blower motor? its possible to motor is seized up.
|
i havent tested it yet but i will... how do you explain the airmix motor not making any sound
|
what year is your car?
|
87

see if that loads for you, if not shoot me a PM I have a diagram or two I can send you. |
yeah it loaded but holy shit i have no idea what im looking at lol im horrible at looking at wire diagrams although i dont think i see any relays on there
|
it cant be just the fan cause when you switch it from cold to hot there is no sound
|
i tested the fan with strait 12 volt source and it works....this really sucks!
|
damn ive been searching and searching and i just cant really find any other helpful info about this on the forum i hope some more people will chime in
|
damn im really starting to lose faith in this forum..

Try swapping out the Logicon.
|

|

Presumably you've already checked the fuses? The FSM says that there is not only the obvious one- 30A "Heater"- but the "Wiper" fuse as well. After that, the point of commonality between the air mix motor and the blower motor is the bloody, already replaced three times, Logicon. You'll have to sort through the wiring diagrams and make sure the Logicon is getting power when the ignition is on since it kinda sounds like it's not. BTW...do the indicator lights on the Logicon come on with the main lighting? |
I had a similar problem. It turned out that the big connector at the back of the dash that the logicon plugs into was bad. If I fiddled with it, the heat would work for a while. I'm going to need to pull the dash to fix the problem.

I have the same exact problem in my 88, if u got it fixed what did you do to fix it? and why would you need to check the wiper fuse if the wipers work? i really need some help because it is below zero right now in the mourning
