Two things
 
I started a new job today. Yeeaaaaaaa!!! 2nd I need to know what I should do. Sell my car, trade it in for another Bonneville, or fix it. I did want another Bonnie like a 95 SSEi or a 96 but I don't want a car note for now. I have some probs withe the white one now like my muffler needs to be changed, I have a hole in it. I need a fuel pump and filter, motor mounts, possibly some trans mounts, a power steering pump, and some tires. May need a new blower for the heat and a/c. Sometimes the car is very hard to start. It cranks but won't turn over on some cold starts or after I cut the engine off to go somewhere and comeback the car doesn't start right away. It might start after 15mins. :evil: :evil: . I don't know if its the 02 sensor, a bad fuel pump, injectors. Then sometimes the car would cut off while driving. Only every blue moon this happens. Is this enough to troubleshoot on?

I say trade 'er

ssesc93 07-15-2003 11:34 PM

Ok. I thought about getting it fixed first, but then I thought about pocketing the money I'll make working and get another Ville. This time an SSEi. I miss the HUD and the Electronic Climate Control.

Jim W 07-15-2003 11:38 PM

I never had it...so, I'm gonna keep the District for a while still and stack the $$$ for the 99.

Trade 'er...oh and congrats on the new job 8)

Congrats on your new job.. I would hold off any imediate plans on trading, buying at the moment till you secure the job ( after the 3 months probation period? ) the last thing you want is to be stuck in more debt.. then if you can afford the insurance and such.. get a newer bonnie and put the old one up as a project car.. or find a newer Poniact bon I Ville ( hee hee. inside jokes that Jim and Muffin knows ) that has no engine and tranny and put that up as a project car. But if you can't afford it or can't decide as to which project car you want to start.. then trade it in. But only after you get permanent.

Why's that?

When I put my blower on the highest level, the fan goes out. It cuts off and on like its a shortage. But when its on the third, second or first level, it works just fine.

Okay, I really doubt there's anything wrong with the blower motor. (When they start to go, the lower speeds fail first.) If only the high speed is cutting in and out, there's most likely a problem in the control circuit.

Do you have the manual dash heat/A/C controls (i.e. three big knobs) or the electronic version? What you're describing sounds like the old high-speed bypass relay problem. Selecting HIGH on the dashboard blower switch would close a relay on the firewall which was used to deliver full voltage to the blower motor for the HIGH speed setting only; all lower speeds went through a resistor pack controlled by the dash switch.

What would happen in the manual control systems (this applies to model years all the way to 1970, give or take a couple years) when the HIGH speed (only) went out was that an in-line wiring harness connector would melt. It was in the 10-gauge wire leading to the bypass relay from the engine. It would look normal, but if you opened the connector you'd find that the contacts had melted the plastic, and separated.

The electronic control system uses a solid-state controller for fan speeds and doesn't really have a HIGH bypass mode; it just cranks the signal voltage all the way to HIGH. (I was playing with the diagnostics on mine this morning to doublecheck error codes before pulling the evaporator, and it was cool to put the controller in diagnostic override mode, select Blower Control, and dial the signal voltage up and down manually, from Gentle Breeze to Hurricane Force. ("Hmmm... current blower speed signal level is 40... Hey, according to the manual I can dial it all the way to 128... Let's see what this baby'll do... :-) ) You might try swapping in a new module if you can borrow a known-good one. It goes in the heater core housing on the firewall under the hood, directly below the relay/fuse center, to the left of the blower motor area.

Hmmmm.....I might have to crank mine up a bit more towards hurricane.....

Heh... well, you don't get to keep that setting; it's just for testing the controller or whatever. But when you're sitting in a quiet garage, the engine's off, and all you hear is this blower motor cranking up faster and faster, it sounds pretty good...

Kind of fun finding out all the things that the controller is monitoring; e.g. not only the outside temperature but also the inside temperature, which isn't usually displayed (you can only get it output in Celsius, unfortunately), plus you can get a reading of the solar intensity sensor for how much sunlight it's picking up, stuff like that. I was able to confirm that the only stored error was for Long-Term Freon Loss, so I cleared that and then started on getting the evaporator out... which is a whole 'nother Subject...
