1991 Subaru Legacy - Page 2 - Answered Questions & Fixed issues

This is a very broad question. When does it happen, in motion, coming to a stop, while you are idle? Where is the noise coming from? The better the detail, the better of an answer. Please let me know

it will be either in a pack of resistors in the heater box or be part of the heater control module in which case the module has to be replaced.

Should be a little window cover on the heater box.

If the car was newer with an OBDII emission system it would trigger the MIL or malfunction indicator light. Being an older computer control system the check engine may not light unless the PCM (powertrain control module) sensed a rich or lean mixture via the oxygen sensor. Does the check engine light turn on with the ignition key on before you actually start the engine?

I believe your referring to the radiator fan & the AC fan next to it. Warm up the car, let the cooling fan come on then put on the AC and see if both fans are running.

check your auto choke

Hi Reese, what do you mean by "won't turn over"? Does the engine rotate but not fire, or does it not even rotate? If it won't rotate, perhaps your alternator belt was loose or worn and the battery didn't get charged. If the battery is good and the engine rotates, then the alternator has possibly died. The other possibility, is that the fuel pump had died.

Possibly bad earth connection, on base plate of distributor or a broken feed wire to points, when the ignition advance works and moves the baseplate, causes intermittent bad running. Good Luck

5 speed, front wheel drive.

depends on the link that is blown . Can be 15,20,30,50 amps depending on what it is running. The amp should be on the ceramic part of the fuse holder.

Any Subaru dealer will be happy to sell you the correct replacement. The Tinker

specify the problem to bring the help

talk to the dealer service center and get their advice on this as some earlier CPU units did not have the plug to allow the reprogramming

what is it , 91 or 99, the blue box above says both!ill answer 91.old car, and this year , limphome mode can be very bad to happen.1: is it tuned up? did you do the 60kmile service schedules? ??????2: is the check engine light on key on, if not fix that now.3: is the check engine light out ,running? yes, pull the DTC errors now.no?if NO CEL running that means this old (dumb) ECU can not see this gross loss of power. This is very possible, reason common , there are 50 reasons.1: engine has low compression, say 80psi not 150+got bad timing belt? if not chain engine. you never stated engine type.2: MAF weak. or inducton air leaks. making MAF LIE.3: EGR stuck open4: fuel pressure low, not doing the 60k skips filter, dah?5: bad spark plugs. 60k.6: air cleaner packed with bugs ,dirt or mouse nest. look.7: injectors clogged8: bad fuel. ill stop and not go 40 more.a mech, knows all these facts. and never considers them.cept the skipped service.he does the tests and lets the results guide him to truth.saving a fortune on guessed at good parts. it called diagnosis.if you want to guess, do so and say so.if you want to do tests. say so, do you want to buy tools? and gauges? say so.To me DIY means doing all that. and not guessingothers DIY means, see what bobby did, and replaced and Ill copy bobby and go broke.it's is your choice.i

No, not even close.

my car was leaking very bad transmission fluid do to my transmission pan so i took it off cleand it up. and found that the pan was a bit warpped and added silicone to new gasket and that fixed my problem for the pan. then i also had to replace the inner and outer seals and now my car dont leak transmission fluid anymore :)

Sounds like the exhaust system is blocked. Have you run the engine with the exhaust off to check ?

Sounds like you have a broken belt for the alternator and power steering.

this is usually called the lower control arm

Your Pump is getting worn, as it expands the noise goes away. You can try and Empty the Power Steering Pump of its fluid and put new in and there is a chance it will go away but if it does not, you are looking at replacing the Pump.Preventive Maintenance goes a long way, the same thing with the brakes, Engine, Transmission, ect.. They all require changing the fluid to prolong the life of the components.
