Saab 900 -93 Foggy (Galway garages for saab)

Posting for a mate

My mate just bought a Saab 900 from 1993 (Turbo S if that makes a difference) which is quite nice but the Driver side floor is wet + the car is fogged up, anyone know what this problem is?

Also, is there a good Garage/person for this age/model Saabs this age in Galway?

Help appreciated!

old blocked pollen filter probably

or blocked drain at the front

check that the coolant level hasn't dropped, you may have a leaking heater matrix.

If it's the "classic" 900 it could also be a rusted-through hole in the windscreen frame under the rubber seal

If it has a sunroof make sure the run off drains are not blocked. Happened to my brother and flooded the car!!

Thanks for fast responses. I should have mentioned it is the "old" shape one with sunroof (yes) and A/C that is slightly dysfunctional from what I understand

Will check the sunroof & seal - can anyone explain where this heater matrix is and where it is located - pics would be very helpful. What does it actually do?

heater matrix is like a radiator in your house with lost of vents in it, hot water from the engine runs through it and the heating fan then blows air through it to heat the air up.


REMOVAL AND INSTALLATION

1. Disconnect the negative battery cable
2. Remove the dash panel under the switches on the steering column and the lower section of the instrument panel.
3. Remove the air diffuser and retaining screws.

Remove the control rod from between the coolant shut off valve and the control rod by sliding the rod
as far forward as it will go to free it from the knob, then pull it rearward to free it from the shut off

NOTE: The plastic joint at the control knob is accessible from underneath once the switches below the
heater controls have been moved backward.

6. Remove the lower section of the heater housing.
Drain the coolant and disconnect the hoses. Plug the ends of the hoses to prevent coolant from leaking

off topic a bit but there was a thread in the classic car section at the start of this month about the saab 900 93 ,some very knowledgeable posts in it ,but not covering your problem . but they might be able to give you some links to owners clubs that might be helpful . good luck with the saab and happy motoring.
